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.
