[phenixbb] B-factors vs resolution

I am refining a 1.3 A structure the maps look great and I notice the main chain B factors are all around 7~12. I have refined the same enzyme at resolution 2.2 A and the B factors here were around 25~30. The question that comes to mind is: Usually one will describe ordered parts of a protein vs disordered parts based on B factors. Is the higher resolution protein more ordered and that may have contributed to its stronger diffraction? Or are the B factors values artifacts of refinement? -- Yuri Pompeu
