Distributions of r
for type I-C, PAM GAA and two different measures of underrepresentation. A, B: Combined ratio for GAA (motif GAA or TTC). Main plots - empirical cumulative density functions (ECDF), Fn - cumulative probability, i.e., the frequency of observations having that rPAM value or a smaller value; gray horizontal line indicates median; inserted plots - distribution as a violin plot . In all plots, the gray vertical line marks rPAM=0; i.e., the observed frequency equals the expected frequency. C, D: Separate ratios for forward strand (motif GAA) and reverse strand (motif TTC).
