Transform	Description
`ReadStructuresFromFile`	Read a file (or files) containing structures and return a PCollection of `Structure` objects.
`WriteStructuresToFile`	Write a PCollection of `Structure` objects to a file.
`ReadMolsFromFile`	Read a file (or files) containing molecules.
`WriteMolsToFile`	Write a PCollection of `Mol` objects to a file.
`FixedSample`	Split a PCollection into two PCollections: a random sample of the input PCollection and the remaining elements.
`Top`	Split a PCollection into two PCollections: the largest n elements of the input PCollection and the remaining elements.
`RandomSample`	Create a PCollection made up of a random sample of the input PCollection.
`Smallest`	Create a PCollection containing the smallest element(s) of the input PCollection.
`IPythonInspect`	Starts an IPython shell to interactively inspect the contents of a PCollection.
`ParetoRank`	Associate inputs with the Pareto front for parameter minimization.

Transform	Description
`LigPrep`	Prepare ligands using LigPrep, turning 2D `Mol`s into 3D structures. LigPrep works by expanding tautomeric and ionization states, ring conformations, and stereoisomers consistent with the input mol to fully capture the relevant states of the molecule in 3D. For each input mol, multiple output structures may be generated.

Transforms for generating 3d structures in a variety of conformations and poses.

Transform	Description
`Dock`	Dock ligands into a receptor using Glide.
`GenerateConformers`	Generate conformers using ConfGen.
`ShapeScreen`	Generate conformers aligned to shape(s).

Transforms for minimizing structures with various methods.

Transform	Description
`FFMinimize`	Minimize a structure using a force field minimization.
`MLFFMinimize`	Minimize a structure using an MLFF model.

Transforms for preparing and refining protein structures.

Transform	Description
`ProteinPrep`	Clean up and prepare a protein using PrepWizard.
`Refine`	Refine a protein receptor using Prime.

Transforms for taking molecules and enumerating new molecules based on them.

Transform	Description
`Decorate`	Decorates a PCollection of `Mol` objects using `RGroup` objects.
`Fragment`	Generate molecular fragments from input `Mol` objects.
`Synthesize`	Combinatorial retrosynthesis of `Mol` objects.

Transforms for filtering collections of molecules based on various criteria.

Transform	Description
`PropertySpaceFilter`	Filters a PCollection of `Structure` or `Mol` objects based on physicochemical property ranges.
`SubstructureFilter`	Filters a PCollection of `Structure` or `Mol` objects based on substructure matches.
