Hi Sara, - what you observe should not happen since phenix.refine uses riding model for H atoms. The hydrogen's B-factors are automatically inherited from the atoms these hydrogens are bonded to. For example, in X-H bond the B-factor of X should be equal to B-factor of H. - make sure you are

Hi Sara, I don't know what "a good average B" is (or what "a bad average B" is). I know that the for the refined structure should fall in the same ball-park range than the temperature factor of the data computed from the Wilson plot. I am not saying that they should match exactly though. If

2010-01-12 Thread Sara Züger
Dear CCP4bb, since the discussion about H-atoms is on, I wanted to ask about what I saw during my refinements: I did refinement with phenix of my 1.9-2.0 Angstroem structures and included the hydrogens (riding). However, when I checked on the statistics (refinement close to the end), the avera
