Hi Jesper,
Can you visualize your trajectories? That is -- load the topology files and
intermediate trajectory files into VMD together to see if they're warped.
Specifically, try to visualize _MMPBSA_mutant_complex.mdcrd with your mutant
complex prmtop (and likewise for the receptor and ligand for both the mutant
and normal forms). Which structures look warped?
Thanks!
Jason
