NMR Refinement
Method	Details	Software
automatic NOE assignment in combination with distance geometry	Refinement of the NOE assignment is performed iteratively. NOAH passes geometrical constraints derived from the NOE list to DIAMOD. DIAMOD calculates a bundle of structures with least violation of the constraints. The new bundle of structures is the basis for refinement of the assignments in NOAH.	NOAH
