Rdkit butina clustering

Webas far as I know, Butina's sphere exclusion algorithm is the fastest for very large datasets. But if you have 4 million compounds, using RDKit directly can result in very long runs, even after parallellization. For that number of molecules I think there are faster things, like chemfp (see for instance Webbutina_cluster.py: Implementation of the clustering algorithm published in: Butina JCICS 39 747-750 (1999) chem_usrcat.py: USRCAT - real-time ultrafast shape recognition with pharmacophoric constraints: filter_catalogs.py: Finds undesireable molecules based on various criteria: gasteiger_charges.py: The Gasteiger partial charges visualization ...
