[gmx-users] can dynamic selection be used with gmx rdf?

Hello all, I would like to calculate the rdf between a set of oxygen atoms in a lipid bilayer to water. But I would like to include in this calculation only a subset of these oxygen atoms that come closer (< 0.3 nm) to Ca ions. I wonder if such a dynamic selection is possible combined with the

Hi, If it was something fundamentally wrong, you'd see an issue before this. Martini is just inherently a teensy bit unstable - but this is where the non-reproducibility of simulations comes in handy; restarting from far enough away will likely avoid a transiently high energy event. Kevin On
