I imagine so, but I'm not an expert on this. Maybe someone else can
comment on how significant a difference the sampling difference makes.
The alternative is to re-run one of your calculations, or possibly
continue your ntwx=250 calculation.

Yes, or just compare to the ntwx=250 part of the ligand run. I.e. stage 1
would be compare the ntwx=500 (selected/aggregated) joint run to the
ntwx=250 portion of the ligand run, then if they agree, compare 250 to 250
ligand/non-ligand.
