Hi Jerome,

CC=1: full correlation;
CC=-1: full anti-correlation.

In terms of electron density maps, CC~0.7-0.8 and up is a good correlation, and lower values indicate poorer correlation.

The numbers you quoted indicate a problem.

Hi:

I am using get_cc_mtz_pdb to compare some structural models and found differences in overall CC around ~0.0056 and local CC around 0.0033.

How much difference in local and overall CC values between two models is generally considered significant?

Thank you,

-Jerome
