Table 2 Similarities between sequences in the three training sets.

Model Type	Number of clusters	Minimum cluster size	Maximum cluster size	Number of Singletons	Average cluster size	Cluster distribution^a
Bacterial	84	1	4	74	1.19	6,2,2
Viral	87	1	5	78	1.15	7,1,0,1
Tumour	76	1	7	66	1.32	4,2,2,1,0,1

For a given cut-off, a perfectly diverse set of sequences will have number of clusters equal to the number of sequences, a maximum and minimum cluster size of one, and an average cluster size of one.
^a for non-singleton clusters of 2 or more members. Cluster numbers are shown in ascending cluster size.
