[gmx-users] Simulation with CsCl

[Cecilia Fernándz Gauna]

Hi all:
I am trying to simulate a polysaccharide in solution of water and CsCl, but
cesium is not parametrized in the gromacs 4. I am using the force
field GROMOS 96.
I have looked for the parameters of Cs+ in the OPLS Force field and I have
created 4 files: Cs.atp, Cs.itp, Csnb.itp and Cs.rtp.  Also I have include
the parameters for Cs+ in the "ions.itp" file, but it didn't work, Can
someone help me?
Thanks in advance.
Cecilia.
