[phenixbb] fix atoms during refinement

[CPMAS Chen]

Dear All Phenix Users,

Is there a way to fix certain atoms position during refinement?

I have some heavy atoms identified with MR-SAD, but when I build the whole
molecule and have phenix to refine its position, the heavy atom's position
is shifted from the anomalous signal. Therefore I would like to have these
heavy atoms positions fixed during refinement.

Thanks!

Charles
