Thread: [Rdkit-discuss] Molecule with no atoms, so is it valid?

WebMay 25, 2012 · I see two choices: 1) As is: Writer generates an empty string, but the parser generates an error 2) Change MolToSmiles so that it generates an error if the molecule has no atoms. I prefer the status quo (choice 1) because I don't really like the idea that a valid molecule would lead to an error in the writer. -greg WebMay 1, 2024 · get_smiles() follows the general pattern for rdkit-cffi functions which operate on molecules: the first two arguments are the pickled molecule and the length of the pickle string, the third argument is a JSON string with additional options to be used when generating the SMILES; in this case we want the defaults, so we pass a NULL pointer (we ...
