According to this
the I-obs(+) column should be type K, and SIGI-obs(+) of type M. It's
possible that phenix does not follow that convention.
As for R-free flags, did you generate them in phenix? If so, the refmac
run with default parameters that pdb does during validation would run
against about 5% of reflections (in phenix test_value=1, in refmac it's
I guess general way to avoid such calamity is to generate test set with
freeflag initially. At this point, you can definitely use something
like sftools to reset the flags so that your model passes pdb validation
with flying colors.
