We would need to see an example of a pdb file that doesn't work. The order
of atoms within a residue should be irrelevant: they do not need to be in
the same order as in the amino acid libraries. (For example, files from
the pdb (RCSB) itself are generally not in the "amber" order either.) I
wonder if your editing is not in fact making some other change as well (?)
