WebApr 14, 2008 · On a related note, I have found that RDKit, when reading SDF files, turns all of the hydrogens into implicit hydrogens. However, when reading SMILES strings, it retains any explicit hydrogens specified in C@@H expressions. This doesn't seem to be consistent and requires the user to remove hydrogens if he/she wants to create a canonical smiles ...
