CSP types are described in Figure 1

p = average proportion of nucleotide difference between pairs of repeat units in the same csp type

Skewness = skewness of the distribution of p values for all pairwise comparisons of nucleotide sequences

Prop. 0 = proportion of pairwise comparisons of nucleotide sequences for which p = 0

Prop.>25 = proportion of pariwise comparisons of nucleotide sequences for which p > 0.25
