WebJan 14, 2024 · With the fingerprint you can either use it directly in the Tree Ensemble or Random forest learner or split it up and use each bit as separate feature. Or you can limit the number of bits to what you seem more suitable albeit obviously losing some information. Still what matters is your goal and the data you have. WebMay 26, 2024 · Note that the RDKit has a method for approximating counts using bit vector fingerprints which is used by the Atom Pair and Topological Torsion fingeprints and could also be an option for the other fingerprint types, but that’s a topic for another post.

However, I sometimes got different results between the two libraries. For example, on the molecule described by the string OCCn2c (=N)n (CCOc1ccc (Cl)cc1Cl)c3ccccc23, which is parsed using RDkit into the following molecule: This … cishet pride flag
