[gmx-users] Using K+ ions

[Vincent Lemaitre]

Hi List!

I would like to perform some MD using K+ cations instead of Na+. 
However, I could not find any description for this ion neither in 
GROMACS nor GROMOS forcefield distributed with Gromacs 3.1.

Has anybody used such an ion for simulation, or at least know where I 
could find the non-bonded parameters for K+?

Many thanks,

Vincent
