Re: [ccp4bb] parameters defining crystallographic model quality

Hi, for example, these qualities below will tell me something about your model: 1. Rfree, Rwork overall and shown in resolution shells; 2. Geometry statistics: - overall rmsd's bonds, angles, ...; - Molprobity statistics/scores; - histograms of deviations from ideal bonds, angels, ...;

I'd head to Gerard Kleywegt's "Practical Model Validation" web course post-haste: http://xray.bmc.uu.se/embo2001/modval/ Eric On Mon, Jan 18, 2010 at 11:00 AM, james09 pruza wrote: > Dear all, > > What are the standard methods for the crystallographic mo

[ccp4bb] parameters defining crystallographic model quality

Dear all, What are the standard methods for the crystallographic model judgment? What parameters should be included in the final refinement statistics in relation to the model error? What is Cruinkshank DPI and how can it be calculated and what information it gives about the quality of the model?
