Understanding G4-clusters and unique features of breakpoints within G4-clusters. a Understanding G4-clusters: The complete square denotes all G4-motifs. The axes apply only to the blue portions of the square and take only integer values. The subset of all singlet G4-motifs (denoted by ‘S’), characterized by exactly 4 ‘G’ triplets (and hence only 1 independent G4), is represented by the grey portion in the top-left region. The blue portions represent G4-clusters. The red line is a bivariate characteristics curve of G4-clusters, the two variables being, number of G triplets and size. Given the number of ‘G’ triplets, the size of G4 cluster can be determined by extrapolation and vice versa. The white ‘˩’ shaped region merely demarcates the unit order and higher order G4 clusters. b Summary of the unique features of breakpoints contained within G4-motifs depicted as a multilevel nested cartoon: The colored bars indicate a unique aspect among the breakpoints present in G4-motifs. Bars are zoomed in at the subsequent level to indicate the features nested within them. The proportion of breakpoints containing the indicated feature is mentioned in each bar
