WebJul 13, 2015 · The reason behind the difference in InChiKeys is that the CHIRAL flag is not set in the attached molfile and openbabel may ignore this. If I put the chiral flag into the molfile, the generated inchikeys are the same. ( It's the "1" in the 4th row in the 4th column). WebMay 12, 2024 · An alternative is using InChIkeys but since they are not human readable, I want to avoid that option. While that is true, InChI strings are human readable, especially for small molecules. In principle only the layers need to be separated by something other than / (underscores would do that). http://inchi.info/inchikey_overview_en.html slow food merida
