Hi Emanuel, The chirality bit doesn't have anything to do with double bond stereochemistry.[1] So that's not what's going on here The RDKit has the ability to pass the mol block provided directly to the InChI code without interpreting it. I believe that the ChEMBL team is using that to generate

Hi Emanuel, the RDKit perceives double bond stereochemistry on read, and encodes on write, based on 2D coordinates in the molblock, I put together an example gist here: https://gist.github.com/ptosco/9ffae8814e84bcf189da7663775748e5 I hope that addresses your question , if not feel free to get

Dear All, I am currently working with the RDKit generated SDF String that is stored in the ChEMBL COMPOUND_STRUCTURES table in the ChEMBL database release 26. My workflow is: - pull SDF (V2000) from SQL table - generate internal molecule representation (NAOMI ChemBio tool-kit if that
