Comparison of performance in yeast for PIC, PIP and their combination. PIC is shown in red, PIP  in green and the combination of PIP and PIC (PIP × PIC) in blue. (a) Receiver operating characteristic (ROC) curves. Both axes are on log-scale. The dashed line shows the diagonal. (b) Precision-recall curves. FP, false positive; N, negative; P, positive; TP, true positive. Positive and negative test sets are as indicated in Table 1.
