[gmx-users] How to calculate protein-surface interaction energy

[Diogo Martins de Sá]

open your .mdp in an editor and under energygrps, add " ProteinSurface"
after the last term.
Run grompp using this .mdp and create a new .tpr. Then use the command
line Justin mentioned last.

 Create a new .tpr with the .mdp file that specifies the desired
energygrps, then:
 
 mdrun -s new.tpr -rerun trj.xtc
