[phenixbb] Rwork/Rfree and aniso ADPs

[Roberto Battistutta]

Dear All,
I have noticed a (too much?) increment in the difference between Rwork  
and Rfree upon introduction of anisotropic ADPs, from 18.6/21.6  
(isotropic ADPs) to 14.5/20.0. The max resolution is 1.6 A with good  
statistics. What could be the reason for that? Is 1.6 A too low for  
anisotropic ADPs in phenix? I would like to keep Rwork/Rfree values  
nearer, how could I do?
Thank you.
Bye, Roberto.
