Hi, 
I would like to perform free energy perturbation using gromacs.
I found some tutorial about this type of calculation, but a question is
not clear.
My calculation is very similar to the calculation described in the
tutorial, because I want to change only the non bonded terms.
I didn't understand if I need to duplicate also the other terms of the
topology file such as bond, angles, pairs, dihedral etc...also when I
don't change this type of terms.
Thank a lot 

Jacopo
