Dear Herman, I am not sure what you really want. Maybe this can help you.
You can get the following numbers out of MAIN 1. comparing a pair of selections. It makes sense only if they are equivalent. > rms b-val select my_selection_1 end select my_selection_2 end 2. Show command does statistics for a given selection. The “bond" keyword considers fluctuations between bonding atoms, whereas without it the selection is considered as one group. > show b-val bond select my_selection end best regards, dusan > On Mar 27, 2015, at 1:00 AM, CCP4BB automatic digest system > <lists...@jiscmail.ac.uk> wrote: > > Date: Thu, 26 Mar 2015 11:32:43 +0000 > From: herman.schreu...@sanofi.com <mailto:herman.schreu...@sanofi.com> > Subject: r.m.s.d.
