PocketMatch
Working of this web interface
Two PDB files whose ligands need to be compared are obtained from the upload
Each of the protein files is then processed to extract all ligands and their corresponding site files
All vs All comparison of sites is done with PocketMatch and scores are reported
If there are M ligands/sites in one protein and N in another, then number comparisons is M*N
Grouping of residues is an important factor in computing the score (ref. Paper)
