schrodinger.protein.predictors module

This module contains classes that wrap prime backends that predict sequence structures. Many of the parameters and class constants are from a time when documentation was sparse. In the future, it’s possible we’ll tweak these numbers as needed.

class schrodinger.protein.predictors.AbstractPredictor(*args, _param_type=<object object>, **kwargs)

Bases: schrodinger.tasks.tasks.SubprocessCmdTask

Base class for all predictors. Derived classes are expected to implement class constants for:

  • EXE - A string that should match to the predictors executable. Most of the time this is the same as PREDICTOR_NAME

  • PREDICTOR_NAME - A string with the name of the predictor. This is used to find the Prime data directory that holds the model parameters used by the predictor.

  • CLASS_NUM - A parameter specific to the predictor. Usually found by looking through the Prime predictors source code.

  • NU - Another model parameter.

  • NY - Another model parameter.

In addition, derived classes should implement the following methods:

generateInputFile - Should generate the required input file at

the file described by input_fname

prediction - Should read self.getLogAsString() and parse out the

actual prediction from the backend

makeCmd - This only needs to be implemented if the backend
takes a command different from the form:

executable model_fname input_fname

EXE = NotImplemented
PREDICTOR_NAME = NotImplemented
CLASS_NUM = NotImplemented
NU = NotImplemented
NY = NotImplemented
class Input(*args, _param_type=<object object>, **kwargs)

Bases: schrodinger.models.parameters.CompoundParam

seq: schrodinger.protein.sequence.ProteinSequence

Base class for all Param classes. A Param is a descriptor for storing data, which means that a single Param instance will manage the data values for multiple instances of the class that owns it. Example:

class Coord(CompoundParam):
    x: int
    y: int

An instance of the Coord class can be created normally, and Params can be accessed as normal attributes:

coord = Coord()
coord.x = 4

When a Param value is set, the valueChanged signal is emitted. Params can be serialized and deserialized to and from JSON. Params can also be nested:

class Atom(CompoundParam):
    coord: Coord
    element: str
aln: schrodinger.protein.alignment.ProteinAlignment

Base class for all Param classes. A Param is a descriptor for storing data, which means that a single Param instance will manage the data values for multiple instances of the class that owns it. Example:

class Coord(CompoundParam):
    x: int
    y: int

An instance of the Coord class can be created normally, and Params can be accessed as normal attributes:

coord = Coord()
coord.x = 4

When a Param value is set, the valueChanged signal is emitted. Params can be serialized and deserialized to and from JSON. Params can also be nested:

class Atom(CompoundParam):
    coord: Coord
    element: str
DataClass

This class can be used to declare a public attribute on a CompoundParam. Declared public attributes can be used without error.

Base class for all Param classes. A Param is a descriptor for storing data, which means that a single Param instance will manage the data values for multiple instances of the class that owns it. Example:

class Coord(CompoundParam):
    x: int
    y: int

An instance of the Coord class can be created normally, and Params can be accessed as normal attributes:

coord = Coord()
coord.x = 4

class Atom(CompoundParam):
    coord: Coord
    element: str
generateInputFile()

Generate the input file for the predictor. Typically includes a header (see _getInputHeader), the file name of the blast alignment, and the sequence to predict properties for.

The input file should be written with the name self.input_fname.

prediction()

Return the actual prediction. This can take various forms depending on the predictor.

generateAlignmentFile()

Write the alignment file to be used as an input for the predictor. The file will be a temporary file and will be removed in postprocess.

Gaps in the alignment file are represented as ‘.’.

generateModelFile()

Generate the model definition file with the name self.model_fname. This is done by finding the Prime data directory for the predictor and getting the names of all the files in it.

The model file includes a header describing the number of model files and the predictors class number (self.CLASS_NUM), and a list of the model files.

makeCmd()

Return the command to run the predictor backend. The default implementation returns the predictor executable, the model file name, and the input file name.

Return type

list[str]

DataClass

This class can be used to declare a public attribute on a CompoundParam. Declared public attributes can be used without error.

Example usage:

class Coord(CompoundParam):

    y: int
    note = NonParamAttribute()

coord = Coord()
coord.note = "hello" # No error

__init__(*args, **kwargs)
addFuncToGroup(func, group=None, order=None)

Adds a function to the specified chain. Typically used for adding functions that are not methods of this object.

The function may optionally be decorated with a FuncGroupMarker. If so, the default group and order will be determined by the decorator. Any group or order explicitly passed in to addFuncToGroup will take precedence over the decorator settings.

Parameters
  • func – the function to add

  • group (FuncGroupMarker or None) – the group marker. If the function is decorated with a FuncGoupMarker, that group marker will be the default.

  • order (float or None) – the sorting order. If the function is decorated with a FuncGoupMarker, the order specified in the decorator will be the default.

addLicenseReservation(license, num_tokens=1)

Add a license reservation for this job. This information is used by job control to ensure the job is only started once the required licenses become available.

In a preprocessor, (i.e. before launching the backend), a reservation should be added for each license that will be checked out directly by that backend. Example:

class GlideTask(ComboJobTask):

    @preprocessor
    def _reserveGlideLicense(self):
        # Reserve a Glide license.
        self.addLicenseReservation(license.GLIDE_MAIN)

    def mainFunction(self):
        # Check out the Glide license
        lic = license.License(license.GLIDE_MAIN)

        # ... Do computations requiring Glide ...

        lic.checkin()

Licenses that will be checked out by subjobs of this job do not need reservations added here; subjobs are responsible for their own license reservations.

Parameters
  • license (module-constant from schrodinger.utils.license (e.g. license.AUTODESIGNER)) – a license that will be used by the backend

  • num_tokens (int) – number of tokens for this license reservations

addPostprocessor(func, order=0)

Adds a postproceessor function to this task instance. If the function has been decorated with @postprocessor, the order specified by the decorator will be used.

Parameters
  • func (typing.Callable) – the function to add

  • order (float) – the sorting order for the function relative to all other preprocessors. Takes precedence over order specified by the preprocessor decorator.

addPreprocessor(func, order=None)

Adds a preproceessor function to this task instance. If the function has been decorated with @preprocessor, the order specified by the decorator will be used as the default.

Parameters
  • func – the function to add

  • order (float) – the sorting order for the function relative to all other preprocessors. Takes precedence over order specified by the preprocessor decorator.

    note = NonParamAttribute()

coord = Coord()
coord.note = "hello" # No error
receivers(self, signal: PYQT_SIGNAL) int
removeEventFilter(self, a0: QObject)
replicate()

Create a new task with the same input and settings (but no output)

requestInterruption()

Request the task to stop.

To enable this feature, subclasses should periodically check whether an interruption has been requested and terminate if it has been. If such logic has been included, INTERRUPT_ENABLED should be set to True.

reset(*args, **kwargs)

Resets this compound param to its default value:

class Line(CompoundParam):
    start = Coord(x=1, y=2)
    end = Coord(x=4, y=5)
line = Line()
line.start.x = line.end.x = 10
assert line.start.x == line.end.x == 10
line.reset()
assert line.start.x == 1
assert line.end.x == 4

Any number of abstract params may be passed in to perform a partial reset of only the specified params:

line.start.x = line.end.x = 10
line.reset(Line.start.x)  # resets just start.x
assert line.start.x == 1
assert line.end.x == 10

line.reset(Line.end)      # resets the entire end point
assert line.end.x == 4

line.start.y = line.end.y = 10
line.reset(Line.start.y, Line.end.y)  # resets the y-coord of both
assert line.start.y == 2
assert line.end.y == 5
run()
runCmd(cmd)
runPreprocessing(callback=None, calling_context=None)

Run the preprocessors one-by-one. By default, any failing preprocessor will raise a TaskFailure exception and terminate processing. This behavior may be customized by supplying a callback function which will be called after each preprocessor with the result of that preprocessor.

This method is “final” so that all preprocessing logic will be enclosed in the try/finally block.

Parameters
  • callback – a function that takes result and returns a bool that indicates whether to continue on to the next preprocessor

  • calling_context – specify a value here to indicate the context in which this preprocessing is being called. This value will be stored in an instance variable, self.calling_context, which can be accessed from any preprocessor method on this task. Typically this value will be either self.GUI, self.CMDLINE, or None, but any value may be supplied here and checked for in the preprocessor methods. self.calling_context always reverts back to None at the end of runPreprocessing.

sender(self) QObject
senderSignalIndex(self) int
setObjectName(self, name: str)
classmethod setParamValue(obj, value)

Set the value of a param on an object by specifying the instance and the value:

# Setting the param value of a basic param
a = Atom()
Atom.coord.x.setParamValue(a, 5)
assert a.coord.x == 5

# setParamValue can also be used to set the value of CompoundParams
c = Coord()
c.x = 10
atom.coord.setParamValue(a, c)
assert atom.coord.x == 10
Parameters
  • param – The owner param to set a subparam value of.

  • value – The value to set the subparam value to.

setParent(self, a0: QObject)
setPrintingOutputToTerminal(print_to_terminal)

Set this task to print StdOut and StdErr output to terminal, or not. This must be set before starting the task to enable terminal output.

Parameters

print_to_terminal (bool) – whether to send process output to terminal

setProperty(self, name: str, value: Any) bool
classmethod setReference(param1, param2)

Call this class method from configureParam to indicate that two params should be kept in sync. The initial values will start with the default value of param1. Example:

class Square(CompoundParam):
    width: float = 5
    height: float = 10

    @classmethod
    def configureParam(cls):
        super().configureParam()
        cls.setReference(cls.width, cls.height)

square = Square()
assert square.width == square.height == 5 # Default value of width
                                          # takes priority
square.height = 7
assert square.width == square.height == 7
square.width = 6
assert square.width == square.height == 6
Parameters
  • param1 – The first abstract param to keep synced

  • param2 – The second abstract param. After instantiation, this param will take on the value of param1.

setValue(value=None, **kwargs)

Set the value of this CompoundParam to match value.

Parameters
  • value – The value to set this CompoundParam to. It should be the same type as this CompoundParam.

  • kwargs – For internal use only.

signalsBlocked(self) bool
skip_eq_check()
specifyTaskDir(taskdir_spec)

Specify the taskdir creation behavior. Use one of the following options:

A directory name (string). This may be a relative or absolute path

None - no taskdir is requested. The task will use the CWD as its taskdir

AUTO_TASKDIR - a new subdirectory will be created in the CWD using the task name as the directory name.

TEMP_TASKDIR - a temporary directory will be created in the schrodinger temp dir. This directory is cleaned up when the task is deleted.

Parameters

taskdir_spec – one of the four options listed above

start(*args, **kwargs)

This is the main method for starting a task. Start will check if a task is not already running, run preprocessing, and then run the task.

Failures in preprocessing will interrupt the task start, and the task will never enter the RUNNING state.

Parameters

skip_preprocessing (bool) – whether to skip preprocessing. This can be useful if preprocessing was already performed prior to calling start.

addFuncToGroup(func, group=None, order=None)

Adds a function to the specified chain. Typically used for adding functions that are not methods of this object.

The function may optionally be decorated with a FuncGroupMarker. If so, the default group and order will be determined by the decorator. Any group or order explicitly passed in to addFuncToGroup will take precedence over the decorator settings.

Parameters
  • func – the function to add

  • group (FuncGroupMarker or None) – the group marker. If the function is decorated with a FuncGoupMarker, that group marker will be the default.

  • order (float or None) – the sorting order. If the function is decorated with a FuncGoupMarker, the order specified in the decorator will be the default.

addLicenseReservation(license, num_tokens=1)

Add a license reservation for this job. This information is used by job control to ensure the job is only started once the required licenses become available.

In a preprocessor, (i.e. before launching the backend), a reservation should be added for each license that will be checked out directly by that backend. Example:

class GlideTask(ComboJobTask):

    @preprocessor
    def _reserveGlideLicense(self):
        # Reserve a Glide license.
        self.addLicenseReservation(license.GLIDE_MAIN)

    def mainFunction(self):
        # Check out the Glide license
        lic = license.License(license.GLIDE_MAIN)

        # ... Do computations requiring Glide ...

        lic.checkin()

Licenses that will be checked out by subjobs of this job do not need reservations added here; subjobs are responsible for their own license reservations.

Parameters
  • license (module-constant from schrodinger.utils.license (e.g. license.AUTODESIGNER)) – a license that will be used by the backend

  • num_tokens (int) – number of tokens for this license reservations

addPostprocessor(func, order=0)

Adds a postproceessor function to this task instance. If the function has been decorated with @postprocessor, the order specified by the decorator will be used.

Parameters
  • func (typing.Callable) – the function to add

  • order (float) – the sorting order for the function relative to all other preprocessors. Takes precedence over order specified by the preprocessor decorator.

addPreprocessor(func, order=None)

Adds a preproceessor function to this task instance. If the function has been decorated with @preprocessor, the order specified by the decorator will be used as the default.

Parameters
  • func – the function to add

  • order (float) – the sorting order for the function relative to all other preprocessors. Takes precedence over order specified by the preprocessor decorator.

killTimer(self, id: int)
max_progress: int

Base class for all Param classes. A Param is a descriptor for storing data, which means that a single Param instance will manage the data values for multiple instances of the class that owns it. Example:

class Coord(CompoundParam):
    x: int
    y: int

An instance of the Coord class can be created normally, and Params can be accessed as normal attributes:

coord = Coord()
coord.x = 4

When a Param value is set, the valueChanged signal is emitted. Params can be serialized and deserialized to and from JSON. Params can also be nested:

class Atom(CompoundParam):
    coord: Coord
    element: str

output: parameters.CompoundParam

All CompoundParam instances are automatically serializable if their subparams are serializable. To serialize and deserialize, use the schrodinger json module:

from schrodinger.models import json
class Coord(parameters.CompoundParam):
    x: int
    y: int

c1 = Coord(x=1, y=2)
c1_string = json.dumps(c1)
c2 = json.loads(c1_string, DataClass=Coord)
assert c1 == c2
outputChanged

# Can be called on an abstract param:
assert Coord.x.owner() == Coord

# ...or on an instance of a CompoundParam
a = Atom()
assert a.coord.owner() == a
classmethod ownerChain()

Returns a list of param owners starting from the toplevel param and ending with self. Examples:

foo.bar.atom.coord.ownerChain() will return [foo, bar, atom, coord] where every item is a concrete param.

Foo.bar.atom.coord.x.ownerChain() will return [Foo, Foo.bar, Foo.atom.coord, Foo.atom.coord.x] where every item is an abstract params.

classmethod paramName()

printingOutputToTerminal()
Returns

whether the StdOut and StdErr output from this task is being printed to the terminal

Return type

bool

processFuncChain(chain=None, result_callback=None)

Execute each function in the specified chain sequentially in order.

The result_callback is called after each function with the return value of that function. This can be used to respond to the return value (e.g. present information to the user, get user feedback, log the result, etc.)

The return value of the result_callback determines whether processing will proceeed to the next function.

Parameters
  • chain (FuncChainDecorator) – which chain to process

  • result_callback – the callback that will get called with the result of each function in the chain

Returns

a list of the results from the functions

progress: int

Base class for all Param classes. A Param is a descriptor for storing data, which means that a single Param instance will manage the data values for multiple instances of the class that owns it. Example:

class Coord(CompoundParam):
    x: int
    y: int

An instance of the Coord class can be created normally, and Params can be accessed as normal attributes:

coord = Coord()
coord.x = 4

When a Param value is set, the valueChanged signal is emitted. Params can be serialized and deserialized to and from JSON. Params can also be nested:

class Atom(CompoundParam):
    coord: Coord
    element: str
progressChanged
progressReplaced

class Atom(CompoundParam):
    coord: Coord
    element: str
progress_stringChanged

property(self, name: str) Any
pyqtConfigure(...)

Each keyword argument is either the name of a Qt property or a Qt signal. For properties the property is set to the given value which should be of an appropriate type. For signals the signal is connected to the given value which should be a callable.

qprocess

This class can be used to declare a public attribute on a CompoundParam. Declared public attributes can be used without error.

Example usage:

class Coord(CompoundParam):
    x: int
    y: int
    note = NonParamAttribute()

coord = Coord()
coord.note = "hello" # No error
receivers(self, signal: PYQT_SIGNAL) int
removeEventFilter(self, a0: QObject)
replicate()

Create a new task with the same input and settings (but no output)

requestInterruption()

Request the task to stop.

To enable this feature, subclasses should periodically check whether an interruption has been requested and terminate if it has been. If such logic has been included, INTERRUPT_ENABLED should be set to True.

reset(*args, **kwargs)

Resets this compound param to its default value:

class Line(CompoundParam):
    start = Coord(x=1, y=2)
    end = Coord(x=4, y=5)
line = Line()
line.start.x = line.end.x = 10
assert line.start.x == line.end.x == 10
line.reset()
assert line.start.x == 1
assert line.end.x == 4

Any number of abstract params may be passed in to perform a partial reset of only the specified params:

line.start.x = line.end.x = 10
line.reset(Line.start.x)  # resets just start.x
assert line.start.x == 1
assert line.end.x == 10

line.reset(Line.end)      # resets the entire end point
assert line.end.x == 4

line.start.y = line.end.y = 10
line.reset(Line.start.y, Line.end.y)  # resets the y-coord of both
assert line.start.y == 2
assert line.end.y == 5
run()
runCmd(cmd)
runPreprocessing(callback=None, calling_context=None)

Run the preprocessors one-by-one. By default, any failing preprocessor will raise a TaskFailure exception and terminate processing. This behavior may be customized by supplying a callback function which will be called after each preprocessor with the result of that preprocessor.

This method is “final” so that all preprocessing logic will be enclosed in the try/finally block.

Parameters
  • callback – a function that takes result and returns a bool that indicates whether to continue on to the next preprocessor

  • calling_context – specify a value here to indicate the context in which this preprocessing is being called. This value will be stored in an instance variable, self.calling_context, which can be accessed from any preprocessor method on this task. Typically this value will be either self.GUI, self.CMDLINE, or None, but any value may be supplied here and checked for in the preprocessor methods. self.calling_context always reverts back to None at the end of runPreprocessing.

sender(self) QObject
senderSignalIndex(self) int
setObjectName(self, name: str)
classmethod setParamValue(obj, value)

Set the value of a param on an object by specifying the instance and the value:

# Setting the param value of a basic param
a = Atom()
Atom.coord.x.setParamValue(a, 5)
assert a.coord.x == 5

# setParamValue can also be used to set the value of CompoundParams
c = Coord()
c.x = 10
atom.coord.setParamValue(a, c)
assert atom.coord.x == 10
Parameters
  • param – The owner param to set a subparam value of.

  • value – The value to set the subparam value to.

setParent(self, a0: QObject)
setPrintingOutputToTerminal(print_to_terminal)

Set this task to print StdOut and StdErr output to terminal, or not. This must be set before starting the task to enable terminal output.

Parameters

print_to_terminal (bool) – whether to send process output to terminal

setProperty(self, name: str, value: Any) bool
classmethod setReference(param1, param2)

Call this class method from configureParam to indicate that two params should be kept in sync. The initial values will start with the default value of param1. Example:

class Square(CompoundParam):
    width: float = 5
    height: float = 10

    @classmethod
    def configureParam(cls):
        super().configureParam()
        cls.setReference(cls.width, cls.height)

square = Square()
assert square.width == square.height == 5 # Default value of width
                                          # takes priority
square.height = 7
assert square.width == square.height == 7
square.width = 6
assert square.width == square.height == 6
Parameters
  • param1 – The first abstract param to keep synced

  • param2 – The second abstract param. After instantiation, this param will take on the value of param1.

setValue(value=None, **kwargs)

  • kwargs – For internal use only.

signalsBlocked(self) bool
skip_eq_check()
specifyTaskDir(taskdir_spec)

Specify the taskdir creation behavior. Use one of the following options:

A directory name (string). This may be a relative or absolute path

None - no taskdir is requested. The task will use the CWD as its taskdir

AUTO_TASKDIR - a new subdirectory will be created in the CWD using the task name as the directory name.

TEMP_TASKDIR - a temporary directory will be created in the schrodinger temp dir. This directory is cleaned up when the task is deleted.

Parameters

taskdir_spec – one of the four options listed above

start(*args, **kwargs)

This is the main method for starting a task. Start will check if a task is not already running, run preprocessing, and then run the task.

Failures in preprocessing will interrupt the task start, and the task will never enter the RUNNING state.

Parameters

skip_preprocessing (bool) – whether to skip preprocessing. This can be useful if preprocessing was already performed prior to calling start.

__init__(*args, **kwargs)
addFuncToGroup(func, group=None, order=None)

Adds a function to the specified chain. Typically used for adding functions that are not methods of this object.

The function may optionally be decorated with a FuncGroupMarker. If so, the default group and order will be determined by the decorator. Any group or order explicitly passed in to addFuncToGroup will take precedence over the decorator settings.

Parameters
  • func – the function to add

  • group (FuncGroupMarker or None) – the group marker. If the function is decorated with a FuncGoupMarker, that group marker will be the default.

  • order (float or None) – the sorting order. If the function is decorated with a FuncGoupMarker, the order specified in the decorator will be the default.

addLicenseReservation(license, num_tokens=1)

Add a license reservation for this job. This information is used by job control to ensure the job is only started once the required licenses become available.

In a preprocessor, (i.e. before launching the backend), a reservation should be added for each license that will be checked out directly by that backend. Example:

class GlideTask(ComboJobTask):

    @preprocessor
    def _reserveGlideLicense(self):

max_progress: int

Base class for all Param classes. A Param is a descriptor for storing data, which means that a single Param instance will manage the data values for multiple instances of the class that owns it. Example:

class Coord(CompoundParam):
    x: int
    y: int

An instance of the Coord class can be created normally, and Params can be accessed as normal attributes:

coord = Coord()
coord.x = 4

When a Param value is set, the valueChanged signal is emitted. Params can be serialized and deserialized to and from JSON. Params can also be nested:

# ...or on an instance of a CompoundParam
a = Atom()
assert a.coord.owner() == a
classmethod ownerChain()

Returns a list of param owners starting from the toplevel param and ending with self. Examples:

foo.bar.atom.coord.ownerChain() will return [foo, bar, atom, coord] where every item is a concrete param.

Return type

bool

processFuncChain(chain=None, result_callback=None)

Execute each function in the specified chain sequentially in order.

The result_callback is called after each function with the return value of that function. This can be used to respond to the return value (e.g. present information to the user, get user feedback, log the result, etc.)

The return value of the result_callback determines whether processing will proceeed to the next function.

  • chain (FuncChainDecorator) – which chain to process

  • result_callback – the callback that will get called with the result of each function in the chain

Returns

a list of the results from the functions

progress: int

    x: int
    y: int

An instance of the Coord class can be created normally, and Params can be accessed as normal attributes:

coord = Coord()
coord.x = 4

qprocess

This class can be used to declare a public attribute on a CompoundParam. Declared public attributes can be used without error.

Example usage:

class Coord(CompoundParam):
    x: int
    y: int
    note = NonParamAttribute()

coord = Coord()
coord.note = "hello" # No error
receivers(self, signal: PYQT_SIGNAL) int
removeEventFilter(self, a0: QObject)
replicate()

Create a new task with the same input and settings (but no output)

requestInterruption()

Request the task to stop.

To enable this feature, subclasses should periodically check whether an interruption has been requested and terminate if it has been. If such logic has been included, INTERRUPT_ENABLED should be set to True.

reset(*args, **kwargs)

Resets this compound param to its default value:

class Line(CompoundParam):
    start = Coord(x=1, y=2)
    end = Coord(x=4, y=5)
line = Line()
line.start.x = line.end.x = 10
assert line.start.x == line.end.x == 10
line.reset()
assert line.start.x == 1
assert line.end.x == 4

Any number of abstract params may be passed in to perform a partial reset of only the specified params:

line.start.x = line.end.x = 10
line.reset(Line.start.x)  # resets just start.x
assert line.start.x == 1
assert line.end.x == 10

line.reset(Line.end)      # resets the entire end point
assert line.end.x == 4

line.start.y = line.end.y = 10
line.reset(Line.start.y, Line.end.y)  # resets the y-coord of both
assert line.start.y == 2
assert line.end.y == 5
run()
runCmd(cmd)
runPreprocessing(callback=None, calling_context=None)

Run the preprocessors one-by-one. By default, any failing preprocessor will raise a TaskFailure exception and terminate processing. This behavior may be customized by supplying a callback function which will be called after each preprocessor with the result of that preprocessor.

This method is “final” so that all preprocessing logic will be enclosed in the try/finally block.

Parameters
  • callback – a function that takes result and returns a bool that indicates whether to continue on to the next preprocessor

  • calling_context – specify a value here to indicate the context in which this preprocessing is being called. This value will be stored in an instance variable, self.calling_context, which can be accessed from any preprocessor method on this task. Typically this value will be either self.GUI, self.CMDLINE, or None, but any value may be supplied here and checked for in the preprocessor methods. self.calling_context always reverts back to None at the end of runPreprocessing.

sender(self) QObject
senderSignalIndex(self) int
setObjectName(self, name: str)
classmethod setParamValue(obj, value)

Set the value of a param on an object by specifying the instance and the value:

# Setting the param value of a basic param
a = Atom()
Atom.coord.x.setParamValue(a, 5)
assert a.coord.x == 5

# setParamValue can also be used to set the value of CompoundParams
c = Coord()
c.x = 10
atom.coord.setParamValue(a, c)
assert atom.coord.x == 10
Parameters
  • param – The owner param to set a subparam value of.

  • value – The value to set the subparam value to.

setParent(self, a0: QObject)
setPrintingOutputToTerminal(print_to_terminal)

Set this task to print StdOut and StdErr output to terminal, or not. This must be set before starting the task to enable terminal output.

Parameters

print_to_terminal (bool) – whether to send process output to terminal

setProperty(self, name: str, value: Any) bool
classmethod setReference(param1, param2)

Call this class method from configureParam to indicate that two params should be kept in sync. The initial values will start with the default value of param1. Example:

class Square(CompoundParam):
    width: float = 5
    height: float = 10

    @classmethod
    def configureParam(cls):
        super().configureParam()
        cls.setReference(cls.width, cls.height)

square = Square()
assert square.width == square.height == 5 # Default value of width
                                          # takes priority
square.height = 7
assert square.width == square.height == 7
square.width = 6
assert square.width == square.height == 6
Parameters
  • param1 – The first abstract param to keep synced

  • param2 – The second abstract param. After instantiation, this param will take on the value of param1.

setValue(value=None, **kwargs)

Set the value of this CompoundParam to match value.

Parameters
  • value – The value to set this CompoundParam to. It should be the same type as this CompoundParam.

  • kwargs – For internal use only.

signalsBlocked(self) bool
skip_eq_check()
specifyTaskDir(taskdir_spec)

Specify the taskdir creation behavior. Use one of the following options:

A directory name (string). This may be a relative or absolute path

None - no taskdir is requested. The task will use the CWD as its taskdir

AUTO_TASKDIR - a new subdirectory will be created in the CWD using the task name as the directory name.

TEMP_TASKDIR - a temporary directory will be created in the schrodinger temp dir. This directory is cleaned up when the task is deleted.

Parameters

taskdir_spec – one of the four options listed above

start(*args, **kwargs)

This is the main method for starting a task. Start will check if a task is not already running, run preprocessing, and then run the task.

Failures in preprocessing will interrupt the task start, and the task will never enter the RUNNING state.

Parameters

skip_preprocessing (bool) – whether to skip preprocessing. This can be useful if preprocessing was already performed prior to calling start.

addFuncToGroup(func, group=None, order=None)

Adds a function to the specified chain. Typically used for adding functions that are not methods of this object.

The function may optionally be decorated with a FuncGroupMarker. If so, the default group and order will be determined by the decorator. Any group or order explicitly passed in to addFuncToGroup will take precedence over the decorator settings.

Parameters
  • func – the function to add

  • group (FuncGroupMarker or None) – the group marker. If the function is decorated with a FuncGoupMarker, that group marker will be the default.

  • order (float or None) – the sorting order. If the function is decorated with a FuncGoupMarker, the order specified in the decorator will be the default.

addLicenseReservation(license, num_tokens=1)

Add a license reservation for this job. This information is used by job control to ensure the job is only started once the required licenses become available.

In a preprocessor, (i.e. before launching the backend), a reservation should be added for each license that will be checked out directly by that backend. Example:

class GlideTask(ComboJobTask):

    @preprocessor
    def _reserveGlideLicense(self):
        # Reserve a Glide license.
        self.addLicenseReservation(license.GLIDE_MAIN)

    def mainFunction(self):
        # Check out the Glide license
        lic = license.License(license.GLIDE_MAIN)

        # ... Do computations requiring Glide ...

        lic.checkin()

Licenses that will be checked out by subjobs of this job do not need reservations added here; subjobs are responsible for their own license reservations.

Parameters
  • license (module-constant from schrodinger.utils.license (e.g. license.AUTODESIGNER)) – a license that will be used by the backend

  • num_tokens (int) – number of tokens for this license reservations

addPostprocessor(func, order=0)

Adds a postproceessor function to this task instance. If the function has been decorated with @postprocessor, the order specified by the decorator will be used.

Parameters
  • func (typing.Callable) – the function to add

  • order (float) – the sorting order for the function relative to all other preprocessors. Takes precedence over order specified by the preprocessor decorator.

addPreprocessor(func, order=None)

Adds a preproceessor function to this task instance. If the function has been decorated with @preprocessor, the order specified by the decorator will be used as the default.

Parameters
  • func – the function to add

  • order (float) – the sorting order for the function relative to all other preprocessors. Takes precedence over order specified by the preprocessor decorator.

qprocess

This class can be used to declare a public attribute on a CompoundParam. Declared public attributes can be used without error.

Example usage:

class Coord(CompoundParam):
    x: int
    y: int
    note = NonParamAttribute()

coord = Coord()
coord.note = "hello" # No error
receivers(self, signal: PYQT_SIGNAL) int
removeEventFilter(self, a0: QObject)
replicate()

Create a new task with the same input and settings (but no output)

requestInterruption()

Request the task to stop.

To enable this feature, subclasses should periodically check whether an interruption has been requested and terminate if it has been. If such logic has been included, INTERRUPT_ENABLED should be set to True.

reset(*args, **kwargs)

Resets this compound param to its default value:

class Line(CompoundParam):
    start = Coord(x=1, y=2)
    end = Coord(x=4, y=5)
line = Line()
line.start.x = line.end.x = 10
assert line.start.x == line.end.x == 10
line.reset()
assert line.start.x == 1
assert line.end.x == 4

Any number of abstract params may be passed in to perform a partial reset of only the specified params:

line.start.x = line.end.x = 10

assert line.start.x == 1
assert line.end.x == 10

line.reset(Line.end)      # resets the entire end point
assert line.end.x == 4

line.start.y = line.end.y = 10

assert line.start.y == 2
assert line.end.y == 5
run()
runCmd(cmd)
runPreprocessing(callback=None, calling_context=None)

Run the preprocessors one-by-one. By default, any failing preprocessor will raise a TaskFailure exception and terminate processing. This behavior may be customized by supplying a callback function which will be called after each preprocessor with the result of that preprocessor.

This method is “final” so that all preprocessing logic will be enclosed in the try/finally block.

Parameters
  • callback – a function that takes result and returns a bool that indicates whether to continue on to the next preprocessor

  • calling_context – specify a value here to indicate the context in which this preprocessing is being called. This value will be stored in an instance variable, self.calling_context, which can be accessed from any preprocessor method on this task. Typically this value will be either self.GUI, self.CMDLINE, or None, but any value may be supplied here and checked for in the preprocessor methods. self.calling_context always reverts back to None at the end of runPreprocessing.

    @classmethod
    def configureParam(cls):
        super().configureParam()
        cls.setReference(cls.width, cls.height)

  • kwargs – For internal use only.

signalsBlocked(self) bool
skip_eq_check()
specifyTaskDir(taskdir_spec)

Specify the taskdir creation behavior. Use one of the following options:

A directory name (string). This may be a relative or absolute path

None - no taskdir is requested. The task will use the CWD as its taskdir

Parameters

taskdir_spec – one of the four options listed above

start(*args, **kwargs)

This is the main method for starting a task. Start will check if a task is not already running, run preprocessing, and then run the task.

Failures in preprocessing will interrupt the task start, and the task will never enter the RUNNING state.

Parameters

skip_preprocessing (bool) – whether to skip preprocessing. This can be useful if preprocessing was already performed prior to calling start.

    coord: Coord
    element: str
model_fname: str

Base class for all Param classes. A Param is a descriptor for storing data, which means that a single Param instance will manage the data values for multiple instances of the class that owns it. Example:

class Coord(CompoundParam):
    x: int
    y: int

An instance of the Coord class can be created normally, and Params can be accessed as normal attributes:

coord = Coord()
coord.x = 4

When a Param value is set, the valueChanged signal is emitted. Params can be serialized and deserialized to and from JSON. Params can also be nested:

class Atom(CompoundParam):
    coord: Coord
    element: str
makeCmd()

Return the command to run the predictor backend. The default implementation returns the predictor executable, the model file name, and the input file name.

Return type

list[str]

generateInputFile()

Generate the input file for the predictor. Typically includes a header (see _getInputHeader), the file name of the blast alignment, and the sequence to predict properties for.

The input file should be written with the name self.input_fname.

rawPrediction()
prediction()

Return the actual prediction. This can take various forms depending on the predictor.

Parameters

json_obj (dict) – A json-loaded dictionary to create an object from.

Returns

An instance of this class.

Return type

cls

classmethod fromJsonImplementation(json_dict)

Sets the value of this compound param value object from a JSON dict.

Warning

This should never be called directly.

getAbstractParam()

Return the corresponding abstract param for this instance.

classmethod getJsonBlacklist()

Override to customize what params are serialized.

Implementations should return a list of abstract params that should be omitted from serialization.

..NOTE

Returned abstract params must be direct child params of cls, e.g. cls.name, not cls.coord.x.

classmethod getParamSignal(obj, signal_type='Changed')
classmethod getParamValue(obj)

Enables access to a param value on a compound param via an abstract param reference:

a = Atom()
assert Atom.coord.x.getParamValue(a) == 0 # ints default to 0
a.coord.x = 3
assert Atom.coord.x.getParamValue(a) == 3
Parameters

param (CompoundParam) – The owner param to get a param value from

classmethod getSubParam(name)

Get the value of a subparam using the string name:

c = Coord()
assert c.getSubParam('x') == 0

Note

Using the string name to access params is generally discouraged, but can be useful for serializing/deserializing param data.

Parameters

name (str) – The name of the subparam to get the value for.

classmethod getSubParams()

Return a dictionary mapping subparam names to their values.

getTypeHint()
get_version()

Method to get the version of a particular object. Defaults to the current version of mmshare. This class can be overridden for custom versioning behavior.

inherits(self, classname: str) bool
initAbstract()
initConcrete()

Override to customize initialization of concrete params.

initializeValue()

Override to dynamically set up the default value of the param. Useful for default values that are determined at runtime. This is called any time the param is reset.

installEventFilter(self, a0: QObject)
classmethod isAbstract()

Whether the param is an “abstract” param.

isDefault()

Whether the current value of this instance matches the default value.

assert Coord.x.owner() == Coord

# ...or on an instance of a CompoundParam
a = Atom()
assert a.coord.owner() == a
classmethod ownerChain()

Returns a list of param owners starting from the toplevel param and ending with self. Examples:

foo.bar.atom.coord.ownerChain() will return [foo, bar, atom, coord] where every item is a concrete param.

Foo.bar.atom.coord.x.ownerChain() will return [Foo, Foo.bar, Foo.atom.coord, Foo.atom.coord.x] where every item is an abstract params.

classmethod paramName()

Get the name of the param:

# Can be called on an abstract param:
print(Coord.x.paramName()) # 'x'

# ...or on an instance of a CompoundParam
a = Atom()
a.coord.paramName() # 'coord'
parent(self) QObject
property(self, name: str) Any
pyqtConfigure(...)

Each keyword argument is either the name of a Qt property or a Qt signal. For properties the property is set to the given value which should be of an appropriate type. For signals the signal is connected to the given value which should be a callable.

receivers(self, signal: PYQT_SIGNAL) int
removeEventFilter(self, a0: QObject)
reset(*abstract_params)

Resets this compound param to its default value:

class Line(CompoundParam):
    start = Coord(x=1, y=2)
    end = Coord(x=4, y=5)
line = Line()
line.start.x = line.end.x = 10
assert line.start.x == line.end.x == 10
line.reset()
assert line.start.x == 1
assert line.end.x == 4

Any number of abstract params may be passed in to perform a partial reset of only the specified params:

line.start.x = line.end.x = 10
line.reset(Line.start.x)  # resets just start.x
assert line.start.x == 1
assert line.end.x == 10

line.reset(Line.end)      # resets the entire end point
assert line.end.x == 4

line.start.y = line.end.y = 10
line.reset(Line.start.y, Line.end.y)  # resets the y-coord of both
assert line.start.y == 2
assert line.end.y == 5

seq: schrodinger.protein.sequence.ProteinSequence

Base class for all Param classes. A Param is a descriptor for storing data, which means that a single Param instance will manage the data values for multiple instances of the class that owns it. Example:

class Coord(CompoundParam):
    x: int
    y: int

An instance of the Coord class can be created normally, and Params can be accessed as normal attributes:

coord = Coord()
coord.x = 4

When a Param value is set, the valueChanged signal is emitted. Params can be serialized and deserialized to and from JSON. Params can also be nested:

setObjectName(self, name: str)
classmethod setParamValue(obj, value)

Set the value of a param on an object by specifying the instance and the value:

# Setting the param value of a basic param
a = Atom()
Atom.coord.x.setParamValue(a, 5)
assert a.coord.x == 5

# setParamValue can also be used to set the value of CompoundParams
c = Coord()
c.x = 10
atom.coord.setParamValue(a, c)
assert atom.coord.x == 10
Parameters
  • param – The owner param to set a subparam value of.

  • value – The value to set the subparam value to.

setParent(self, a0: QObject)
setProperty(self, name: str, value: Any) bool
classmethod setReference(param1, param2)

Call this class method from configureParam to indicate that two params should be kept in sync. The initial values will start with the default value of param1. Example:

class Square(CompoundParam):
    width: float = 5
    height: float = 10

    @classmethod
    def configureParam(cls):
        super().configureParam()
        cls.setReference(cls.width, cls.height)

square = Square()
assert square.width == square.height == 5 # Default value of width
                                          # takes priority
square.height = 7
assert square.width == square.height == 7
square.width = 6
assert square.width == square.height == 6

setValue(value=None, **kwargs)

Set the value of this CompoundParam to match value.

Parameters
  • value – The value to set this CompoundParam to. It should be the same type as this CompoundParam.

  • kwargs – For internal use only.
