Figure 4.

Accuracy of transferred sequences detection. RIATA-HGT (best scenarios selected) and Prunier (fast version) results are respectively indicated by triangles and circles. The color code corresponds to the different support values tested as a threshold for topological conflict significance. The figure represents the positive predictive value as a function of the negative predictive value (see Material and Methods) of the two methods. Black lines represent the limits given by RIATA-HGT on true trees. These statistics show how often predictions are correct when sequences are classified as transferred (PPV) or not transferred (NPV). A perfect method would have PPV = 1 and NPV = 1.
