PROP_SOURCE = 3

class Input(*args, _param_type=<object object>, **kwargs)

Bases: schrodinger.models.parameters.CompoundParam

seqs: List[schrodinger.protein.sequence.AbstractSequence]

A Param to represent lists. Values of this param will have a mutated signal that will be emitted whenever any mutation method is called.

The constructor optionally takes a item_class keyword argument to specify what type of class the items in the list will be. This information will be used for jsonifying the list if specified.

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):
    x: int
    y: int
    note = NonParamAttribute()

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

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.

Resets this compound param to its default value:

class Line(CompoundParam):
    start = Coord(x=1, y=2)
    end = Coord(x=4, y=5)

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.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

run()

runCmd(cmd)

@overrides: tasks.AbstractCmdTask

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.

runToCmd(skip_preprocessing=False)

Does the same thing as start except it doesn’t actually launch the job. Instead it just returns the final job cmd.

Intended to be used for running jobtasks on JobDJ, which requires a job cmd rather than a task.

sender(self) → QObject

senderSignalIndex(self) → int

setJob(job: schrodinger.job.jobcontrol.Job)

” Use given jobcontrol.Job to incorporate job results into the task and run postprocessors. Example:

task = FooTask()
cmd = task.runToCommand()
job = jobcontrol.launch_job(cmd)
job.wait()
task.setJob(job)

If the job has not been downloaded, the task will be set to FAILED with a SetJobRuntimeError.

Parameters

job – jobcontrol.Job with results to incorporate into the task.

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

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.

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(skip_preprocessing=False)

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.

A factory method which constructs a new object from a given dict loaded from a json string or file.

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.

incorporation_file: TaskFile

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

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.

runCmd(cmd)

@overrides: tasks.AbstractCmdTask

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.

runToCmd(skip_preprocessing=False)

Does the same thing as start except it doesn’t actually launch the job. Instead it just returns the final job cmd.

Intended to be used for running jobtasks on JobDJ, which requires a job cmd rather than a task.

sender(self) → QObject

senderSignalIndex(self) → int

setJob(job: schrodinger.job.jobcontrol.Job)

” Use given jobcontrol.Job to incorporate job results into the task and run postprocessors. Example:

job.wait()
task.setJob(job)

If the job has not been downloaded, the task will be set to FAILED with a SetJobRuntimeError.

Parameters

job – jobcontrol.Job with results to incorporate into the task.

    @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

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(skip_preprocessing=False)

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.

startTimer(self, interval: int, timerType: Qt.TimerType = Qt.CoarseTimer) → int

staticMetaObject = <PyQt6.QtCore.QMetaObject object>

status: Status

statusChanged

statusReplaced

stop()

taskDirSetting()

Returns the taskdir spec. See specifyTaskDir() for details.

taskDone

taskFailed

taskStarted

thread(self) → QThread

timerEvent(self, a0: QTimerEvent)

toDict()

Return a dictionary version of this CompoundParam. The returned dictionary is fully nested and contains no CompoundParam instances

a = Atom()
a_dict = a.toDict()
assert a_dict['coord']['x'] == 0
assert a_dict['coord'] == {'x':0, 'y':0}

toJson(_mark_version=True)

Create and returns a data structure made up of jsonable items.

Return type

An instance of one the classes from NATIVE_JSON_DATATYPES

toJsonImplementation()

Returns a JSON representation of this value object.

Warning

This should never be called directly.

tr(sourceText: str, disambiguation: typing.Optional[str] = None, n: int = - 1) → str

valueChanged

wait(timeout=None)

Block until the task is finished executing or timeout seconds have passed.

Warning

This should not be called directly from GUI code - see PANEL-18317. It is safe to call inside a subprocess or job. Run git grep "task.wait(" to see safe examples annotated with “# OK”.

Parameters

timeout (NoneType or int) – Amount of time in seconds to wait before timing out. If None or a negative number, this method will wait until the task is finished.
