Hi Daniele, the number of resolution bins is determined automatically to allow a significant number of test reflections per bin (that is enough to: - estimate ML parameters, - compute Rfree). The default value is "free_reflections_per_bin=140" which is found empirically (by running many refinement trying different values) to be the best. Pavel.

Hi,

I was wondering how phenix.refine decide the number of resolution bins in which it shows the refinement statistics (R-free, phase error...). In the case I'm working on it prints out only three resolution bins.

Thanks
