  1. a, divergent SNVs are all those SNVs that differ between at least two strains, i.e., all identified strains are considered as diverged taxonomic units, and polymorphic SNVs are all the invariant SNVs. b, Divergent SNVs have the same state inside a strain clade and are not invariant and polymorphic SNVs are all the remaining, i.e., only the clades are considered as diverged taxonomic units
