WebOct 15, 2024 · The key feature for determining chiral tags in RDKit is the order of the bonds in the Mol object. We will therefore use the following strategy: Reorder the bonds in the Mol object so that they match the order in the SMARTS pattern Set the chiral tags of each matched atom so that they match the SMARTS pattern

WebSep 1, 2024 · RDKit Version: 2024.09.1; Platform: Pop OS 18.04 LTS (Ubuntu 18.04 LTS) When removing and adding the same bond the chirality sometimes changes if the new bond has a higher idx than before. I am not a chemist but from my understand rdkit is using the order of the bonds to determine order in which different R groups added to the chiral center. WebApr 1, 2015 · Does RDKit generate a random conformation, or no specific conformation in the first place? By default no conformation is generated, but if you ask the RDKit to generate a 3D conformation (or conformations), it will attempt to generate one that matches whatever stereochemistry is specified.
