Figure 6. Identity threshold tuning.

Figure 6

(A) Number of clusters obtained by clustering RdRP palmprints of 2,048 recognised ICTV species at identity thresholds 97%, 96% … 85%. (B) Number of species that are split over multiple OTUs, lumped together with one or more other species into a single OTU, both lumped and split (Lmp+Spl), or pure (not lumped or split). The best fit of number of clusters to number of species is obtained at 90% identity.
