[gmx-users] Ryckaert-Bellemans type dihedral

[Suman Chakrabarty]

Hi,

I need to write my own topology file for a system using
Ryckaert-Bellemans type dihedral potential. Since I should remove the
1-4 non-bonded interaction in this case, I wanted to know whether it is
enough not to keep any [ pairs ] entry in the topology file (manual page
113), or I should explicitly put nrexcl as 4 in the [ moleculetype ]
section. What is the full-proof method of using RB potential?


Thanks,
Suman.
