Dear gmxusers,

I am investigating intracellular proteins and NA+ ain¹t the answer.

Why is there no definition for K+ for GROMOS96 ff in the ions.itp file???
I¹m using gromacs3.3.1

Yet it¹s in the GROMACS ff and OPLS sections of the ions.itp file.

Is there a solution to this if I am using GROMOS96 force fields?

Thanks in advance.
