btw you only need explicit 1-4 for charmm when the 1,4 from the original charmm prm is actually different/specified (i.e. non-conjugated carbons) -- Sent from my Android phone with K-9 Mail. Please excuse my brevity.

S. Soares wrote: Dear users, In GROMACS, does CHARMM36 ff, calculate eventual 1-4 interactions that are absent from the [pairtypes] section of the ffnonbonded.itp file? I ask this because I'm converting cholesterol parameters from CHARMM36c to gmx format, and several 1-4 values are absent in the last two columns of the prm file. Does setting gen_pairs to "yes" in the [defaults] section in the forcefield.itp work? Probably. What documentation exists is probably in the walk-through example of manual 5.7.1. You can probably construct yourself a trivial test case if you wish to verify how things work.
