The code is based on the Python implementations of Jan Domanski and Adrian Schreyer. Most of the time you get the exactly same result, but for some molecules the difference can be quite large (here's a random molecule from MolPort as an example): The molecule looks like identical in KNIME. 4570000. These examples are extracted from open source projects. I noticed whenever I built 3D conformers of molecules containing piperazine (or cyclohexane) using RDKit, I tend to get a distorted ring conformation. . We will do that by looking a similarities between random "drug-like" (MW<600) molecules picked from ChEMBL. class rdkit.Chem.rdMolDescriptors.AtomPairsParameters ((object .
