the command that I used is : g_energy -f md300.edr -s fws_md300.tpr -o energy.xvg -pairs pairs.xvg

There is no reason for g_energy to be reading a topology to extract this information. You can get so-called "nonbonded interaction energies" decomposed by energy group, but whether or not you can call this an actual "binding energy" is highly questionable. -Justin -- ======================================== Justin A.
