From: Self consistency grouping: a stringent clustering method
SCG, CL, AL, and SL clustering results of SCOP domains based on structural similarity score. The same color scheme was used as in Fig 3. The graph represents the cluster sizes (X axis) and the corresponding number of clusters (Y axis). This figure shows that all clustering methods yielded many small clusters or singletons and few big clusters. Note that the clusters with sizes greater than 5 are all lumped together.
