WebAug 24, 2024 · The TL;DR summary: When working with the RDKit's Morgan2 fingerprint (MFP2), I think it's reasonable to fold the fingerprints down to 128 bits, particularly when using higher similarity thresholds. This balances the number of hits missed against the number of extra hits retrieved and can result in significant performance improvements … WebMay 20, 2015 · The Tanimoto index, Dice index, Cosine coefficient and Soergel distance were identified to be the best (and in some sense equivalent) metrics for similarity calculations, i.e. these metrics could produce the rankings closest to the composite (average) ranking of the eight metrics.
