Procheck puts out such a correlation (% most favorable
vs resolution) in the _04.ps file. For example look at
page 7, first panel of the sample procheck output at:
http://sb20.lbl.gov/SQR/procheck-2H88.pdf
It appears that 83.5% would be well above average
for a 3 A structure according to procheck statistics.
(However I think most structures nowadays are
"above average" by procheck statistics)

Dear all,
I am now preparing my structure for deposition. The
crystal diffracts to 3.0 A. R: 0.20; R free: 0.25.
What I am concerned with is the Ramachandran plot;
83.5% in core region, 15.8% in allowed, 0.5 % in
general allowed,0.2% in disallowed region. The model
fits in density pretty well and all the attempts to
improve Ramachandran have not been successful after
quite a few trials. I am wondering if 83.5 % in core
region is acceptable with 3.0 A resolution data?
Moreover, is there some numeric correlation between
diffraction resolution and model Ramachandran? Thank
you for your help.
