No. You'd have to strip away all non-protein components from the 
trajectory, make a matching .tpr file, and use mdrun -rerun. Then you'll 
get the protein's potential energy, which also happens to be a 
meaningless quantity.

[gmx-users] Protein potential energy

2018-06-18 Thread Ming Tang
Dear list,

I pulled a protein in water. In order to get the trend of the potential energy 
terms of the protein, I defined energygrps and reran the system. May I ask can 
I get the right trend of the protein potential energy terms using this approach?

Your help is appreciated.
Thanks,
Tammy
