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.
