The labels need to actually be present in the MTZ file.  The file
you're using (assuming it's the same one you sent us earlier) only
contains amplitudes and R-free flags.  For this particular application
(and phenix.fit_loops as well), you need to supply map coefficients -
it won't calculate them on the fly.
