Re: [phenixbb] Validation question: R-factor (all) and # of unique reflections (all)

Hi Young-Jin,

I feel like I should calculate R(all). As mtz file is usually big, how can I extract Fobs and Fmodel from phenix generated mtz file?

If you feel you want it, then go ahead, and this command might be of help here: phenix.mtz.dump data.mtz --column-data-format=spreadsheet -c Yet another (easier) alternative is to run a dummy phenix.refine run like this: phenix.refine data.mtz model.pdb xray_data.r_free_flags.ignore_r_free_flags=true main.number_of_mac=1 strategy=none output.prefix=junk then take the reported R-factor (Rwork will be equal to Rfree, so take any of them), and discard the files. All the best! Pavel.
