[gmx-users] generate pair list and 1-4 interactions

I am a bit confused about how the pair potentials (PPs)are calculated.
If I state explicitly sigma and epsilon values for the pair potentials,
can I then still have a coulomb scaling of my 1-4 interactions?
Say I set "gen-pairs" to "yes", although I have all possible pair
potential interactions specified under "[ pairtypes ]", would I then
still be able to scale my 1-4 coulomb interactions by setting a
"FudgeQQ" different from 1? Also, would I be able to scale the already
given van der Waals interactions with "FudgeLJ"?
Finally, are generated pair potentials based on the parameters specified
under "[ atomtypes ]" or "[ nonbond_params ]" (if the latter exist) in
the ffamber03nb.itp file?
