MAPP score distributions. (a) The distribution of MAPP scores (M_sc) for core promoter (CP) and negative (NEG) sequences are given for the test dataset Test1. Upper and lower limits of the box represent the upper and lower quartiles of the distribution, respectively. Whiskers extending from the boxes represent the extent of the rest of the data distribution, while outliers are represented by magenta points. On the right-hand side of the dotted line is the breakdown of the NEG distribution into separate distributions for intergenic (IG) and exonic (EX) sequences. (b) The specificity (blue squares) and sensitivity (red circles) at different M_sc thresholds.
