Any idea what might be causing this? I can send a link to the sdf file that I’m processing if that’s useful. Below is the traceback.

Hi Sean. Thanks for your message. I’ve never seen this error before. It appears to be a problem with RDKit, one of Gypsum-DL’s dependencies. Can you share the specific SMILES string that led to this error so I can debug? Thanks.

This error arose while processing a virtual library built from ZINC building blocks. I’m not exactly sure which compound was to blame, but I will narrow it down and post a SMILEs string for a problematic compound in a bit.
