[phenixbb] ADP: fix_wxu and wxu_scale

[fulvio saccoccia]

Dear Phenix users and developers,
	I'm trying to refine a 3 A resolution structure. In order to better
understand how can I use wxu_scale and fix_wxu options in phenix.refine,
may you explain me their use, since I have a lot of problems with ADPs?
In fact, I have big variations between atoms of the same residue.
So, is it better to use wxu_scale or to impose fix_wxu to refine the
ADPs?

Thanks to all
