This plot shows a histogram of the numbers of restraints within each distance range for all the upper- and lower-bound distance restraints. The bars are coloured according the the proportion of these restraints that are violated in the models making up the ensemble.
The plots are split both according to the type and class of distance restraint. The types comprise: NOE restraints, Hydrogen-bond restraints and S-S disulphide restraints.
The classes are as defined in the General parameters; namely, Long, Medium or Short.
The main options for the Numbers of distance restraints plot are:-
These options can be altered by editing the parameter file, procheck_nmr.prm, as described here.
