Some entries in the Protein Data Bank contain an ensemble of structures which are consistent with the raw data from the
structure determination experiments. This situation is most common in structures determined by NMR spectroscopy. A MODEL
record identifies each set of coordinates in the PDB file. This search allows querying the PDB by the number of models
in the file.
Select the appropriate choice from the left hand menu ("=", ">", "<", "!=") and enter an integer number in the text box.
