Hi PC,
The two methods will give related but not identical results.
If you say
phenix.autobuild data=solve_2.mtz hires_file=w1.sca seq_file=seq.dat
then the file AutoBuild_run_1_/expts_fobs_phases_freeR_flags.mtz will
contain:
FP SIGFP from w1.sca, converted from intensities to amplitudes.
PHIB FOM HLA HLB HLC HLD from solve_2.mtz
FreeR_flags generated by phenix.refine
If you go to the GUI and use phenix.reflection_file_editor you can get a
similar result if you select
"all columns" from w1.sca, and select "edit arrays" and choose "output
reflections as" amplitudes"
and you select all the columns from solve_2.mtz EXCEPT FP SIGP
This will yield:
F+ SIGF+ F-SIGF- from w1.sca
PHIB FOM HLA HLB HLC HLD from solve_2.mtz
FreeR_flags generated by phenix.refine (not identical to the ones above
from autobuild)
In your case as you are supplying anomalous data in w1.sca (I assume) it
may be easiest to let autobuild do it for you as it will merge the F+ and
F- while the reflection file editor won't do that quite as easily.
All the best,
Tom T
