Hi Nilesh, To center the solute with respect to the solvent, first center the solute in the box, and then put the solvent in the box. Mind that that involves two passes of trjconv.
If 'no pbc effect' means no wrapping over the boundaries, yes you can use -dump with -pbc nojump to save a snapshot. trjconv will go over the frames and 'unwrap' the frames before the snapshot you want. Hope it helps, Tsjerk On Mon, Oct 17, 2011 at 9:18 PM, Nilesh Dhumal <ndhu...@andrew.cmu.edu> wrote: > Ya, I want to center solute w.r.t to the solvent. > > I have more question, if I want to save the coordinates of a snapshot with > no pbc effect, can I use -pbc nojump in trjconv. > > nilesh > > On Mon, October 17, 2011 1:34 pm, Tsjerk Wassenaar wrote: >> Hey :) >> >> >> The reference plays no role in centering.
