It's not that atom numbering is sequential - it's that the atom range
in the molecule is not completely contiguous. So something like this:
Molecule 1: Atoms 1 2 3 4 10 11 12 13
Molecule 2: Atoms 5 6 7 8 9
Cpptraj (and I think other programs in Amber as well) operates on the
assumption that molecules are completely contiguous (this is
beneficial for a lot of reasons). When they aren't, cpptraj kicks back
this error. I think parmed will give you a similar warning.

Can you elaborate on *exactly* what you did and describe exactly why
it didn't work? We need way more information to help.
