I have trouble understanding the statement "The output from SCALA give
the completeness of about 97 to 99%". Overall completeness is just one
number. Completeness in bins is a bunch of numbers, which are
completeness per resolution bin. Completeness may be in range (eg. from
d_min to d_max) or from d_min to inf. Sometimes they may be very
Anyway, when it comes to refinement, phenix.refine log file reports
initial reflection statistics somewhere at the very beginning of log
file: this is what actually in your input reflection file. Later on
phenix.refine may (or may not) remove a few reflections as outliers,
which is also reported in the log file. I guess same information is
obvious in the GUI as well.
So what exactly is your question?
