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. WebThe threshold values used by the Tanimoto and Dice filter operators are mapped to two expressions defined in module :py:mod:`razi.postgresql_rdkit`: >>> from razi.postgresql_rdkit import tanimoto_threshold, dice_threshold >>> session.scalar (tanimoto_threshold), session.scalar (dice_threshold) (u'0.5', u'0.5')
