WebMar 31, 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. WebDec 10, 2024 · In our case, we use RDKit ETDKG to create the initial geometry (and the initial 3D .mol file) so yes, the atoms will match. Well, some versions of the CREST program from the Grimme group do atom reordering, which was annoying. If we're using Open Babel later, we use --gen3d to create the initial .mol file and again, it will match atom order.
