Hi Rizwan,

The code has changed A LOT between amber 6 and amber 9 so you will have a
lot of work to do to merge things in. You might also want to consider doing
this with AMBER 10 instead of AMBER 9.

In AMBER 9 the essence is that runmd() calls force(). For GB calculations
this calls egb() which calculates the nonbond and GB terms. For explicit
solvent simulations this calls ewald_force which does the reciprocal and
direct space calculations. The direct space is via a call to get_nb_energy()
which is in short_ene.f

In short there is no way simple grepping for AMBER 6 variables is going to
help you. You need to trace through the code from force.f downwards into
get_nb_energy and associated routines.

Good luck,
Ross
