Class cohesion of three virus datasets. The four columns illustrate the separability and compactness of three virus complete genomes datasets based on 172 restriction enzyme cuts. The first column shows heatmaps of CUT clustered by x-axis. The samples in the y-axis are grouped by studied classes followed by intra-class clusterings. The second column shows MDS of the CUT distances between samples. The third and fourth column represent, respectively, the Cohesion and Silhouette indexes of the classes. a Classes in HPV are Alpha species, Beta and Gamma genera. b Classes in HBV are A-H genotypes c Classes in HIV-1 are M pure subtypes and CRFs
