[gmx-users] Hello

So the problem is that .tpr file has peptide shifted in another box as after g_rms with -pbc option, RMSD is still ~1.5A => .tpr file generated from .mdp file during grompp programme, has peptide away from its usual position. I am giving pbc = xyz in .mdp file as well. Why then .tpr file should have peptide displaced ?


Regards,
Nikhil

So? You need to compare that with pre-simulation...

Try trjconv like my link suggested.
