Hi,
After JED's email I tried immediately:
case:
a metal site which has very strong density and a HIS co-ordinating
with the ion. After I click 'Real space refine zone' and then the residue
HIS, the HIS will move to the density which belongs to the ion(clash with
the ion) no matter how low the weight was set.
PS, I remember that Xfit of XtalView has the beauty to avoid this
kind of problem, but now I am a regular user of coot.
Thanks
Yanming
