Crystallographic b-factors

WebIn crystallography, the R-factor (sometimes called residual factor or reliability factor or the R-value or R Work) is a measure of the agreement between the crystallographic model and the experimental X-ray diffraction data. In other words, it is a measure of how well the refined structure predicts the observed data. [1] WebThe B-factor is a measure of the uncertainty of the atomic position, which includes the effects of noise due to model errors and lattice defects, in addition to the positional variance of thermal protein motion. The amount of noise is generally lowest for the highest-resolution structures (<1 Å).
