[gmx-users] LJ-PME with user defined non-bonded parameters

Hi, gmx users,
I am trying to use the LJ-PME to include to the long-range vdw forces in my
simulations. It seems to me that when I enabled LJ-PME, I cannot
arbitrarily modify the nonbonded parameters in my topology file, because
those parameters must satisfy the geometric or arithmetic combination rule.
Otherwise Gromacs generates a note that " You are using geometric
combination rules for LJ-PME, but your nonbonded C6 parameters do not
follow these rules." Am I right? If so, is there any other way to account
for the r^-6 interactions in reciprocal space?
Good luck and happy simulating.
