Well it depends how the OP has set up their simulation. Was trying to help. :) What you're saying is right of course. On 2 July 2016 at 21:45, Justin Lemkul wrote: > > > On 7/1/16 9:51 PM, Billy Williams-Noonan wrote: > >> Hi Justin, >> >> I've found that I get this error with my relative FE

Hi Justin, I've found that I get this error with my relative FEP calculations if my .gro file with the relevant protein and ligand coordinates, describes the protein numbering from a1-3017, and the ligand from 3018 onwards for example, while in my topology file, a1-3017 refer to the same protein,
