Description

ECIFP is an interaction fingerprint for analyzing protein-ligand contacts, binding site and binding mode similarities.

This software provides methods for:

Generating Extended Connectivity Interaction Fingerprints (ECIFP) for protein-ligand complexes in the PDB
Identifying and analyzing binding sites
Computing binding mode and binding site similarity
Comparing protein-ligand interaction patterns
