Thanks Justin, that makes sense! I'm wondering why none of the other proline residues triggered that warning though? The same procedure works like a charm with other proteins. On 7 Oct 2015 10:59 pm, "Justin Lemkul" wrote: > > > On 10/7/15 3:01 PM, Dries Van Rompaey wrote: > >>

Thanks for explaining, (and Professor Farais de Moura as well) that makes sense. On a different note, I've noticed a huge difference in performance between my equillibration run and my actual simulation, and I'm wondering if this is normal. For comparison, I ran a couple small (meaningless)

If ALL the particles are changing with the free energy coupling parameter, then GROMACS will slow down quite a bit. If only one molecule is changing, then it shouldn't be that much slower (20-30% slower?) But without .mdp and.top files, it's hard to say exactly what is happening. On Wed, Oct
