[phenixbb] on B-factor refine of the phenix.real_space_refine

Hi,

I would not recommend having H given that you are likely refining 
against >4A resolution map.

Not sure I understand this. I would say they are different because they 
went through refinement, so why it is unexpected to you?

No. It must be a bug in your system.

If you do not provide resolution in input using keyword "resolution=.." 
it will try to estimate it given model and map. This may or may not be 
accurate, and the way it is estimated is different from any available 
software.

Hope this answers some of your questions!
