Comparison of P scores of the positive datasets with P scores of the shuffled and partially shuffled datasets. In the legend of this figure, ‘0’, ‘5’ and ‘10’ represents the shuffled, the partially shuffled (±5) and the partially shuffled (±10) datasets, respectively. The x-axis represents the nucleotide position and the y-axis is the P score of (A) QKI and (B) Nova. The black boxes are the RBP-bound sites, and the horizontal dotted lines the corrected significance levels of the Bonferroni correction. The vertical dotted lines indicate the ±5 or 10 nucleotides of RBP-bound sites. RBP, RNA-binding protein.
