Receiver Operator Characteristic curves for PSWMs as operon predictors. ROC curves are shown for all 14 PSWM sets built and applied to E. coli. Legend refers to: Significance threshold or Data set_Clustering threshold_Number of clusters for a) Positive predictive Value (TP/(TP+FP)) vs sensitivity (TP/(TP+FN)), and b) Specificity (TN/(TN+FP)) vs sensitivity (TP/(TP+FN)).
