Try alternate rotamers first, and then choose the closest to the 'right' electron density, before you do 'real space refine' Regards, Josiah.
Hi, I use coot almost around the clock. One thing troubles me is that: when clicking on 'real space refine zone', coot seems only care about the 'real space'(Electron density), sometimes it will bring the model to the density no matter whether the density was already claimed by other model atoms or not, resulting in clash and unreasonable geometry. How can I avoid this? Sorry for an old crystallographer to ask so babyish question. But your help can save me lots of time. Thanks Yanming
