Dear Phenix Community, I am preparing my structure for deposition and ran it through the Generate "Table 1" function in phenix. The inputs I gave it were my .mtz structure factors file, the final pdb coordinate file, and the log file from hkl2000. I did not provide unmerged data. My pdb file (which had been refined using phenix.refine) had values of r_work=0.2342 r_free=0.2603 However, phenix.model_vs_data (from Generate "Table 1") gave me r_work=0.2940 r_free=0.3150 I also got this warning about resolution limits, but I think it should not have affected the R-free calculation to this extent: WARNING: Resolution limits in scaling log for structure A549T are inconsistent with resolution limits in the MTZ file: 50.00 - 3.02 (in logfile) 48.47 - 3.03 (in MTZ file) When I refined my model in phenix, I used the twin law h,-h-k,-l. I read in the documentation that twinning can account for some of this discrepancy, but that the program is supposed to take twinning into account if it will lower the calculated R-work by more than 2%, which it doesn't seem to have done (or there is some other problem with my data). Thanks for your help! -Sam
