WebSep 27, 2024 · RDkit Discussion Group, I note that RDkit can perform Butina clustering. Given an SDF ofsmall molecules I would like to cluster the ligands, but obtain additionalinformation from the clustering algorithm. In particular, I would like to obtainthe cluster number and Tanimoto distance from the centroid for every ligandin the SDF. WebJun 28, 2024 · For fingerprint similarity analysis, we first need to get the fingerprints for each molecule. For such purpose we type: In [5]: fps= [FingerprintMols.FingerprintMol(mol) for mol in working_library] As result we have n fingerprints as n molecules: In [6]: print(len(working_library)) print(len(fps)) 100 100. And we can get the similarity for each ...
