WebMay 18, 2024 · The goal here is to systematically come up with some guidelines that can be used for fingerprints supported within the RDKit. We will do that by looking a similarities between random “drug-like” (MW<600) molecules picked from ChEMBL. For the analysis, the 25K similarity values are sorted and the values at particular threshold are examined. WebJan 21, 2024 · The RDKit produces a fingerprint that has 167 bits so that the numbers of the bits (which are always indexed from zero) correspond to the number of the key (bit 0 is always 0). So MACCS key 43 is bit 43 in the RDKit implementation. It would be 42 in the CDK implementation.
