[gmx-users] Can 1-4 interactions be excluded seperately?

[Bo Zhou]

Hi all,

There are two molecules in my system. One is parameterized with no torsion
term in the energy expression (consistent with the OPLS force field), so 1-4
interactions should be excluded. The other one is treated as a normal
protein molecule using OPLS force field. I want to include OPLS ff, but not
to gen pairs with the previous molecule. Does it feasible in gmx?
Thanks in advance.
