Dear Branden, Dear Hans attached to this email is a patch to correct file atp.chem for the molecular composition of the molecule, i.e. the missing nitrogen atom. As suggested by Branden, as a basis for discussion. After January, once Hans' additional bond types enter chem, an additional revision to yield a more contemporary depiction could be sensible.
