A linear text format which can describe the connectivity and chirality of a molecule, and has a single "canonical" form for any particular molecule, regardless of atom order. Write Options e.g. -xt i Includes isotopic and chiral markings n No molecule name t Molecule name only
See also, the "regular" SMILES format, which results in faster output, since no canonical numbering is performed.
