Combined assignment and dynamics algorithm for NMR applicationsCYANA is a program for automated structure calculation of biological macromolecules on the basis of conformational constraints from NMR. The combination of automated NOESY cross peak assignment, structure calculation with a fast torsion angle dynamics algorithm.CYANA package include previous DYANA system, that uses simulated annealing combined with molecular dynamicsin torsion angle space (torsion angle dynamics).
