Dear developers,

I would like to know the exact definition of the total potential energy with
respect to protein-solvent interactions, in an explicit solvent protein 
simulation.

For protein atom Pm and solvent atom Wn, there are two interactions:

Pm to Wn
Wn to Pm

Are both interaction energies counted in the total potential energy given in the
log file or by g_energy?

If I want to compute the total potential enery of the protein, plus
protein-solvent interactions, should I then only add half of the protein-solvent
terms given by g_energy? I am only interested in the effect of solvent "felt" by
the protein, and not in the effect of the protein felt by the solvent.

Thank you very much for your help!

Pascal
