In other words, it is a measure of how well the refined structure predicts the observed data. [1]

WebMar 1, 1991 · Crystallographic refinement by simulated annealing with molecular dynamics has been applied to a 2.8 A (1 A = 0.1 nm) resolution X-ray structure of aspartate aminotransferase, achieving structural changes and improvements of the electron density maps that were not possible by using restrained least-squares refinement without … WebRefinement based on [math]I [/math], the measured intensities, has the merit of using the raw measurements directly, although it requires the incorporation in the refinement of the correction factors (scale factor, Lorentz–polarization and absorption) that are applied during standard data reduction. biology class 9 past papers fbise
