[gmx-users] Energy contribution of individual residues

You do not need to run the simulation anew, you can make use of mdrun -rerun, which uses an existing trajectory but a new tpr file, with new energy groups for instance.
That said, it is often impossible to decompose the energy exactly into separate contributions from, say, individual residues.

I had set energygrps as "Protein LIG" (LIG for ligand). I have gone through the archives, but these do not tell much and say that the results may not be accurate, and because of shortage of time, I cannot do the production run again with setting energygrps for individual residues. Do you happen to know any other good tool?
