PDB files for NMR models

At first glance, the averaged model would appear to serve most researchers who are looking for a molecular model to help them explain the function of the molecule and rationalize other chemical, spectroscopic, thermodynamic, and kinetic data. On the other hand, you might think that the ensemble and distance-restraint files are of most use to those working to improve structure determination techniques. There are good reasons however, for all researchers to look carefully at the ensemble, as discussed in the next section. 

As with PDB files for crystallographic models, NMR coordinate files also include headers containing citations to journal articles about the structure determination work, as wel3 as brief descriptions of specific techniques used in producing the model presented in the file. When you view PDB files in web browsers, the literature citations contain convenient live links to Medline abstracts of the listed articles.
