Issue with dimer MD with gmx editconf -translate

Have a look at this post: Protein/Ligand complex amber production question - #2 by alevilla and this thread: Mdp parameters for non-bonded interaction using the AMBER force field - #6 by fatemeh. There seems to be a range of “valid” settings for the amber force fields. But the ones in the first post should be OK, as far as I know.
