Performance improvement ratio (PIR) by the integrated score over the average performance of iREAD and IRFinder in terms of AUC. PIR was calculated for both the 15 M (a) and 30 M (b) datasets using the three different gold standard set of retained introns: GS1(FPKM≥0.1), GS2 (FPKM≥0.3) and GS3(FPKM≥0.5). PIR decreases as a function of increased numbers of positive retained introns, suggesting that iREAD and IRFinder complement most each other for the top ranked introns
