WebJun 5, 2024 · I notice that if I pass a mol object (derived from a molblock with the chiral flag set) through GetMolFrags(), the resulting chiral molecules do not have the chiral flag set when new molblocks are generated. I include a molfile at the end that can be used to demonstrate this with the code below. sanford nc elementary school
