- 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

- 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 theself.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, theref_mols
will be ignored.- class Settings(*args, _param_type=<object object>, **kwargs)¶
