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 mea
