Threshold and range distributions of MRCs (a) Numbers of maximally representative clusters (n ≥ 4), as a function of maximum threshold expressed as S'_norm; (b) numbers of maximally representative clusters (n ≥ 4), as a function of minimum threshold expressed as S'_norm. Note the 1531 MRCs at S'_norm = 0.01; (c) numbers of maximally representative clusters (n ≥ 4), as a function of range of maximality (extent along S'_norm). The range of maximality of a maximal cluster is the length of the internal edge immediately subtending it.
