Hi all when we use "gmx energy" what is the difference between LJ-(SR), LJ-14, Coulomb-14, Coulomb(SR)? those mentioned energies, give us energy interaction of total system. right?
Not necessarily, because there may be long-range terms from PME or dispersion correction.
if I want to determine interaction enenrgy for example, LJ, between two special species, not in total system, what should I do?
Define energygrps in the .mdp file and re-evaluate the energies of the trajectory with mdrun -rerun. Note that for most force fields, this value has no physical significance.
