[phenixbb] anisotropy and mtz edit

[Pavel Afonine]

Hi Leonid,

phenix.refine does anisotropic scaling as described here:

A robust bulk-solvent correction and anisotropic scaling procedure.  P. 
V. Afonine, R. W. Grosse-Kunstleve and P. D. Adams  Acta Cryst. D61, 
850-855 (2005).

I would be interested to revisit this problem at some point: could you 
please send me (to my email): data before and after anisotropy 
correction, and best current model so I can see effect on the maps. I 
can't promise to do anything right now, but I'm collecting the cases so 
I have a handful of examples the moment when I'm ready to work on it.

Thanks!
Pavel.
