Where are you working?
>From my experience the g_energy -fee only gives a free enrgy estimate for the whole system, so one has to pull out all the energy terms based on your index file of interest and sum them in a spread sheet. if the -fee can do the energy estimates for a specific set, please let me know this would be valuable to me.

> Betreff: [gmx-users] Free energy between residues
> Dear Gmx Users,
> I want to obtain the free energy difference between the pair of
> residues in my protein chain with respect to thheir distance. Would
> 1) g_dist - distances between two groups during the simulation time
> 2) g_energy -fee (DelatG - with energy groups I am interested in
> stated in mdp file)
> give me those values?
> Or I should use PMF - umbrella sampling with the bias (harmonic)
> potential introduced?
