[phenixbb] Problematic dataset

[Pavel Afonine]

Hi all,

one minor remark:

> phenix.refine twinning=True twin_law=<whatever xtriage gives you> 
> model.pdb data.mtz

in the latest phenix.refine it is not necessary to say twinning=True. 
Providing  twin_law=<whatever xtriage gives you> is enough to tell 
phenix.refine to use twin specific refinement protocols.

The keyword "twinning=True" was removed as an element of redundancy.

Pavel.
