Hi Justin,
I have
free-energy              = no
in my .mdp file, but I still see this value in g_energy.
It should be absent or always 1 while the values by g_energy are close to 1 but
still fluctuating along the trajectory.
So, can you explain me how the value is used by gromacs?


Sorry, what I said before was wrong. I mistook the energy term. It's actually related to temperature coupling and shows up when using Berendsen or V-rescale. The actual term is defined in the original 1984 Berendsen coupling paper (eq 10 and 11).
