[gmx-users] Scaled 1-5 interactions

[Borys Szefczyk]

Dear GROMACS Users,

I would like to use the OPLS force field, but with additional scaling
factor for the Coulomb 1-5 interactions for certain atoms. More precisely,
I want to use the standard 0.5 scaling for Coulomb and LJ 1-4 interactions
and 0.8 scaling factor for Coulomb 1-5 interactions. Is there a way to
do this within the topology file of Gromacs or do I need to modify the code?

Regards,
Borys Szefczyk
