[gmx-users] Interaction Energies for QSAR analisys

[Monique Brito]

Hi,

We are doing MD simulations just for
obtaining the interaction energies
of a ligand-protein complex in vacuo.

The program that perform the ligand
topology, PRODRG available in web,
just works in the force field 
4 of the GROMACS (GROMOS 87), which
works with a water box.

Is there any problem in using this force
field for doing calculations in vacuo?
Is it necessary to add some parameter in 
.mdp file to correct the dielectric
constant?

We suppose that there is not any
problem, since the interaction energies
of a set of ligand-protein complexes
will be used in a QSAR analisys.

Thanks in advance,
