WebA procedure has been developed for the refinement of crystallographic protein structures based on the biomolecular simulation program Amber. The procedure constructs a model representing a crystal unit cell, which generally contains multiple protein molecules and is fully hydrated with TIP3P water. WebCrystallography & NMR System Initial refinement by simulated annealing, minimization, and B-factor refinement First simulated annealing using torsion angle dynamics is used to improve the model. The use of torsion angle dynamics reduces the number of parameters being refined and hence reduces the degree of overfitting of the data. http://web.mit.edu/pmueller/www/Watkin_2008.pdf cty logistics

WebSep 11, 2024 · In crystallography, refinement is crucial because of the phase problem: the accuracy of density maps relies on the accuracy of the phases of the structure factors. … WebThen, refinement is performed using the remaining 90%. The R-free value is then calculated by seeing how well the model predicts the 10% that were not used in refinement. For an ideal model that is not over-interpreting the data, the R-free will be similar to the R-value. Typically, it is a little higher, with a value of about 0.26.
