Hi Carl,
the R-factors seem reasonable given the resolution... Try running
phenix.validate from the latest version: it will do all Molprobity
analysis, compute map CC for each residue, draw POLYGON image, and do
many other validation staff. That might help to spot if there is
anything not right.
I'm not sure correlation of what with what you mention below, so hard to
comment.
