WebJun 12, 2024 · Our atom-pair fingerprint is designed similarly to the AP fingerprint implemented by RDkit. AP encodes atom pairs using atomic invariants combined with their bond distances. Instead of using atomic invariants, we use the circular environment of each atom in the pair up to a preset radius, written as canonical SMILES, similar to the method … WebMar 27, 2024 · rdkit - MACCS Fingerprint - Stack Overflow MACCS Fingerprint Ask Question Asked today Modified today Viewed 4 times 0 When I perform a Python heatmap of similarity search I can't seem to get the heatmap that actually creates a comparison.

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. http://rdkit.org/docs/
