NMR Refinement
Method	Details	Software
simulated annealing	sa.inp script of X-Plor NIH tutorial followed by 3 cycles of refine.inp (from X-PLOR NIH). Structures with no violations selected for next round. multiple cycles of prot_sa_refine.inp from this site (https://nesgwiki.chem.buffalo.edu/index.php/Structure_Refinement_Using_XPLOR-NIH) until no violations. Structures have no differences the human eye can see but have better PDB quality bars.	X-PLOR NIH
