[gmx-users] using g_enemat

[sadhna]

hi all,
       I want to calculate VdW interactions between atoms in protein using
g_enemat option but i am confused about the -groups option.
Do I have to make an input file with different atoms in different residues
in pairs so that it would output the interaction energies between atom
pairs....could any one provide me with the sample of input file for
-groups option.


thanks
