WebOct 25, 2024 · I'm producing MACCs keys with the "RDKit Fingerprint" node, and I am noticing that I am getting 167 bits instead of 166. The node description acknowledges that there should be 166 bits for MACCs. Not sure where this extra bit could be coming from. Also, the "Fingerprints" node (from CDK) gives the correct number of bits. WebMolecular Fingerprinting encodes a Simplified Molecular Input Line Entry Specification (SMILES) as a fingerprint.

WebThe RDKit can generate conformations for molecules using two different methods. The original method used distance geometry. [1] The algorithm followed is: The molecule’s distance bounds matrix is calculated based on the connection table and a set of rules. The bounds matrix is smoothed using a triangle-bounds smoothing algorithm. 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.
