Well, seems easy, I got a molecule with gromos parameters but the ATB site state the use of new force field, this new forcefield defined new atom label like CPos, when i started to fill with ions to neutralie charge i got the message

CPos not found

i wonder why?

i follow the instructions as the README file state, but the problem persist, the comand applie were:

gmx grompp -f mdp/ions.mdp -c gfdo_solv.gro -p topol.top -o ions.tpr

the topol.top has the right files:

#include "./gromos54a7.ff/forcefield.itp"

#include "./gromos54a7.ff/ffnonbonded.itp"

#include "./gromos54a7.ff/spc.itp"

#include "./gromos54a7.ff/ions.itp"

#include "gfdo.itp"
