To give some context, it's not that we're trying to sample a diverse set of conformers (and find something close to the experimental). In this case, we're generating initial geometries - to assess Naruki's fragment-based builder in Open Babel. But you raise an excellent point - by picking only one

Hi Naruki, You're only generating a single conformer per molecule; I wouldn't expect that to do particularly well. It's generally better to call EmbedMultipleConfs(). As an aside: I've looked at the platinum set too, it might be worth checking out this RDKit blog post: http://rdkit.blogspot.com/2

[Rdkit-discuss] Evaluating ETKDG method with the Platinum Dataset

Dear all, I'm evaluating ETKDG method implemented in RDKit using the Platinum Dataset introduced in a benchmark paper https://pubs.acs.org/doi/abs/10.1021/acs.jcim.7b00505/ SMILES generated from the dataset is served as input and a 3D conformer is generated. We evaluate RMSD between generated stru
