StereoMolGraph (SMG) is a library for graph representation of molecules and reactions with a focus on Stereochemistry. It provides:
- Graph types for molecules and reactions (with/without stereo and stereo changes)
- Includes non tetrahedral stereocenters and changing stereochemistry in reactions
- Fast approximate hashing via Weisfeiler–Lehman color refinement
- Robust equality/isomorphism via a VF2++-style algorithm extended for stereochemistry and reactions
- Bidirectional conversion from / to RDKit
- Construction from 3D coordinates with automatic local stereo inference
- Unopinionated about bond orders, charge and electronic state
- SMG focuses just on the connectivity and stereochemistry.
- Stereochemistry describes relative spatial arrangement. No absolute stereochemistry.
- Transparent: Simple 2D visualization in IPython notebooks
- Hydrogens must be explicit for bidirectional conversion.
- Supports tetrahedral and non tetrahedral stereochemistry during conversion.
- Bond orders, charges, unpaired electrons and other properties are not used!
