Package schrodinger :: Package analysis :: Module transformations

Module transformations

Module to support chemical transformations defined via reaction SMARTS (RDKit dialect).

Transformations can be applied either individually using apply_transform(), or "en-masse" via apply_transforms() (see below).

TransformsRepository class supports loading of the transformations from files (or text) in JSON format.

apply_transform(st, rxn, core=None, f3d_engine=None, logger=None)
Applies single transformation and generates (smiles, st, core) tuples for the outcomes.

apply_transforms(st, transforms, core=None, f3d_engine=None, logger=None)
Applies transformations to structure.

apply_transform(st, rxn, core=None, f3d_engine=None, logger=None)

Applies single transformation and generates (smiles, st, core) tuples for the outcomes.

Parameters:

st (Structure) - Input structure.
transforms - Reaction to be performed.
core (iterable) - Indices of the atoms that must be kept unchanged.
f3d_engine (fast3d.Engine instance.) - fast3d handle to be used for 3d coordinates generation (omitted if None).
transform (ChemicalReaction instance.)

apply_transforms(st, transforms, core=None, f3d_engine=None, logger=None)

Applies transformations to structure.

Generator of the (Structure, smiles, core, route) tuples.

Parameters:

st (Structure) - Input structure.
transforms (list of lists of ChemicalReaction instances.) - List of lists of reactions to be performed.
core (iterable) - Indices of the atoms that must be kept unchanged.
f3d_engine (fast3d.Engine instance.) - fast3d handle to be used for 3d coordinates generation (omitted if None).
