CGRTools

Tools for processing of reactions based on Condensed Graph of Reaction (CGR) approach.

Basic operations:

• Read/write/convert formats: MDL .RDF (RXN) and .SDF (MOL), .MRV, SMILES, INCHI (Linux and Windows), .XYZ, .PDB

• Standardize molecules and reactions and valid structures checker.

• Duplicate searching.

• Tetrahedron, Allene and CIS-TRANS stereo checking.

• Produce CGRs.

• Perform subgraph search.

• Build/edit molecules and reactions.

• Produce template based reactions and molecules.

• Atom-to-atom mapping checker and rule-based fixer.

• Perform MCS search.

• 2d coordinates generation (based on SmilesDrawer)

• 2d/3d depiction.
