Information provided by these studies has deeply and extensively enriched and shaped our vision of the virus world.
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]
