  1. Mean site-level sensitivity (sSn), positive predictive value (sPPV) and area under the ROC curve (AUC) for five collections of realistic synthetic data at varying levels of motif conservation. In these tests, the motif discovery phase of the algorithm was removed and the set of candidate models constructed as if the motif discovery algorithm had performed as well as possible at each candidate width.
