Dear Gromacs users:

I am trying to extract the constraint energy imposed by position restraint.
I extract the coordinate of the restraint atom and want to calculated
directly by using the harmonic potential. The question is : Does the
reference position come from the .gro file as the input in mdrun? It seems
to me that that's the only possible source as I didn't specify it anywhere.
