Yes you are right, all I am getting is:
Loading and checking parameter files for compatibility...
mmpbsa_py_energy found! Using
/home/AAData/AMBER/amber14/bin/mmpbsa_py_energy
cpptraj found! Using /home/AAData/AMBER/amber14/bin/cpptraj
Preparing trajectories for simulation...
I have added comma as well but no difference. I think I must be missing
something else or making a mistake somewhere else but unable to point my
finger to that..
Best Regards,
Asma
