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. Pavel.
