Histogram of cluster sizes for SCOP Fold level. The frequency of occurrence is plotted against the size of clusters obtained by hierarchical clustering using the Fold-level distance threshold. As for the SCOP Superfamily level, pairwise MATT distances result in a large number of small clusters, including many singletons. In comparison, for MPSS, a smaller number of larger clusters which map more directly to the SCOP Fold classification are obtained.
