schrodinger.application.steps.filters module

Filter steps that take input Mols and only outputs Mols that meet certain criteria.

NOTE::

You can import UniqueSmilesFilter from this module, which will either be InMemoryUniqueSmilesFilter or BQDedupeChain (which will filter using BigQuery) depending on whether you have the environment variable SCHRODINGER_GCP_KEY defined.

You can generally use UniqueSmilesFilter for your workflows and users will define SCHRODINGER_GCP_KEY as needed when they scale higher, but if you know a part of your workflow will be low-volume then it would be better to use InMemoryUniqueSmilesFilter instead.

All of the above also applies to RandomSampleFilter, which also has an in-memory and bigquery variant.

class schrodinger.application.steps.filters.InMemoryUniqueRandomSampleFilter(*args, **kwargs)

Bases: schrodinger.stepper.stepper.Chain

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

Bases: schrodinger.models.parameters.CompoundParam

n: 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

seed: int

    @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

class schrodinger.application.steps.filters.CloudOptionMixin

Bases: object

A mixin that allows the task a choice between cloud based or in-memory.

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

Bases: schrodinger.models.parameters.CompoundParam

use_cloud_services: bool

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.

Example usage:

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

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

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.

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

class schrodinger.application.steps.filters.ProductFilterMixin

Bases: object

A mixin that only allows molecules through whose SMARTS substructure count passes all product filters defined in the settings.

If the settings has cflt_file defined, it will be considered to be the path from which to create the smarts_filter to use.

Since the filter.SmartsFilter can checkStructure with either Mol or Structure objects the behavior is completely determined by the class that it is a mixin for, i.e., either an MolMapStep or MaeMapStep.

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

Bases: schrodinger.models.parameters.CompoundParam

Variables

• smarts_filter – the smarts filter or None

• cflt_file – if defined the source to

cflt_file: schrodinger.stepper.stepper.StepperFile

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.

Example usage:

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

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

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

cflt_file: schrodinger.stepper.stepper.StepperFile

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

class schrodinger.application.steps.filters.PropertyFilter(*args, **kwargs)

Bases: schrodinger.application.steps.basesteps.MolMapStep

Only allows molecules through whose properties pass all property filters defined in the settings.

If the settings has filter_file defined, it will be considered to be the path from which to create the filters to be used.

If the filter filename has the .json extension, it will be interpreted as a JSON filter file of the kind used by a few panels, including PathFinder; that filter format is implemented by schrodinger.ui.qt.filter_dialog_dir.filter_core.

A file without the .json extension is considered to be regular text with the format of the filter file is that of what pathfinder and canvas filter uses, e.g., lines like:

r_rdkit_TPSA > 30.0 < 150.0
i_rdkit_NumRotatableBonds < 10
i_rdkit_NumChiralCenters == 1
r_rdkit_MolWt > 150.0 < 575.0

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

Bases: schrodinger.models.parameters.CompoundParam

filter_file: schrodinger.stepper.stepper.StepperFile

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.

Example usage:

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

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

The property_ranges should be a dict where the key is the property name (a string that exists in filtering.DESCRIPTORS_DICT). The value should be the range of values allowed for that property where the ends are included in what is considered to be acceptable.

property_ranges: Dict[str, List[float]]

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

The constructor optionally takes a value_class keyword argument to specify what type of class the values will be. This information will be used for jsonifying the dictionary if specified. (Note that non-string keys are not currently supported for jsonification. This may change in the future. See PANEL-13029).

class schrodinger.application.steps.filters.ProfileFilter(*args, **kwargs)

Bases: schrodinger.application.steps.basesteps.MolMapStep

A product filter where the property profile is defined by the settings.

The complexity_max is a dictionary with the property name as key and the value above which the complexity is incremented. If the total complexity exceeds max_complexity the molecule is rejected.

Example in yaml notation:

ProfileFilter:
    property_ranges:
        MolWt: [250, 500]
        FractionCSP3: [0, 1]
        AlogP: [-1, 4]

ProfileSettings

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

Bases: schrodinger.application.steps.filters.ProfileSettings

core_complexity: Dict[str, int]

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

The constructor optionally takes a value_class keyword argument to specify what type of class the values will be. This information will be used for jsonifying the dictionary if specified. (Note that non-string keys are not currently supported for jsonification. This may change in the future. See PANEL-13029).

max_complexity: 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

large_ring_cutoff: 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

class schrodinger.application.steps.filters.FepFilter(*args, **kwargs)

Bases: schrodinger.application.steps.basesteps.MolMapStep

Only allow molecules through that are amenable to FEP calculations.

A molecule is considered to be amenable if it is an acceptable perturbation with settings.min_edges other molecules in the self.settings.ref_mols.

A perturbation is considered acceptable if the number of heavy atoms in the perturbation from the maximum common substructure (MCS) is less than or equal to settings.max_hac_diff.

The settings contain the following parameters:

• fep_references_file: the title-less SMILES file with SMILES in the 0th column (the way that Maestro exports them…)

• ref_mols: the list of references (Chem.Mol objects)

• min_edges: the minimum number of edges needed

• max_hac_diff: the maximum number of heavy atoms not part of the MCS

if the fep_references_file is defined, the ref_mols will be ignored.

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

Bases: schrodinger.models.parameters.CompoundParam

fep_references_file: schrodinger.stepper.stepper.StepperFile

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

ref_mols: List[rdkit.Chem.rdchem.Mol]

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.

min_edges: 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

max_hac_diff: 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 Settings(*args, _param_type=<object object>, **kwargs)

Bases: schrodinger.models.parameters.CompoundParam

min_value: float

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

max_value: float

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.

Example usage:

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

coord = Coord()

class schrodinger.application.steps.filters.MaxMolWtSettings(*args, _param_type=<object object>, **kwargs)

Bases: schrodinger.models.parameters.CompoundParam

A compound param that defines a maximum molecular weight.

max_mol_wt: float

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.

Example usage:

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

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

class schrodinger.application.steps.filters.SortedScoreFilter(*args, **kwargs)

Bases: schrodinger.application.steps.dataclasses.ScoredSmilesIOMixin, schrodinger.stepper.stepper.ReduceStep

A filter that will return the first max_out number of scored SMILES, after they have been sorted with a sort order determined by the reverse setting.

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

Bases: schrodinger.models.parameters.CompoundParam

reverse: bool

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

max_out: 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

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

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(*args, **kwargs)

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(*args, **kwargs)

classmethod getParamValue(*args, **kwargs)

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.

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'

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.
