Selection of the most relevant 4-mers. Sample in from the hyper-negatively supercoiled pFC53 R-loop data set. The first column is the ranking <i>n</i> of the 4-mers in after ordering them by weight. The second column lists all the 4-mers where 4-mers with the same ranking are listed in the same field. In this sample the total number of 4-mers in is 115. The third column indicates the weight of <i>s</i>_<i>n</i>. The last three columns illustrate the steps of the selection procedure for determining the cutoff point: weight rescaling, entropy calculation, and average entropy computation. The cutoff point–highlighted–is the maximum of the average entropy values.
