[phenixbb] Phenix.Refine: Missing High Resolution Data

[Mark A. White]

Hello,

I have several data sets which seem to loose completeness in their
high-resolution shells when the HKL *.sca file is converted into an MTZ.
I am using the recommended Diederichs CC1/2 cut off of 0.5, which is
usually an I/s <2.  I also have an usually high redundancy in these data
sets, not sure if that has any effect.  Here is a typical comparison of
the Phenix statistics and the HKL values.  Note that the resolution bins
do not match, and that the Phenix refinement was truncated to 3.0Å.
