simulated annealing, molecular dynamics	Computed through AMBER9 in water, Computed through AMBER9 in water. Single residues in some models have phi-psi angle combinations that are outside the norm. These are found only for residues that lack experimental constraints and which are therefore poorly defined in the structure.	NMRPipe
