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 Jerome C.

Sorry, I meant average differences...

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. Pavel. On 5/27/11 8:04 AM, Jerome Nwachukwu wrote:
