Hi Henrik,
Well, it happens when your coordinates extracted dont match the coordinates
which you specify in the mm_pbsa.pl script when you calculate the energies.
You will be surprise that the generation of snapshots dont give error. When
you submit your receptor, ligand and complex file if you have used ptraj, it
ll add up residue one atom number more for every TER whereas your snapshots
wont have atom number assigned to TER.
The other problem could be you are running out of virtual memory. If you are
able to run the tutorial properly then there is no memory problem.

Neha
