Hi Ana,

can I see input and output files used for refinement please? It's next 
to impossible to make meaningful comments without seeing the files. In 
general phenix.refine does not removes reflections unless a few outliers 
or unless requested by the user (such as resolution or/and sigma cutoffs).

I am aware that the data collection statistics should be calculated in the same resolution range of refinement. Do you know the reason of this difference? I just followed the instructions from HKL where I indexed and scaled and then used Phenix for MR and refinement.
