If this helps, the .prmtop file in question was a legacy from AMBER 11,
but worked fine as input for AMBER 14 sander runs on multiple platforms.

When attempting to load a .prmtop file into cpptraj, I get the following
error message:
Error: Atom 6415 was assigned a lower molecule # than previous atom.
This can
Error: happen if 1) bond information is incorrect or missing, or 2) if the

Error: the 'setMolecules' command in parmed.py.
Error: Could not determine molecule information for MycGMIV.prmtop.
Error: SetSolventInfo: No molecule information.
Error: Could not determine solvent information for MycGMIV.prmtop.
I tried 'fixatomorder", no difference.
If it helps, atom 6415 is the first K+ ion used to solvate and balance
charge.
Any suggestions?
Thanks,
Tom Pochapsky
