Figure 7.

A comparison of the accuracy of SPR and MRP supertrees with known or unknown gene tree roots. The upper panels compare the mean supertree error (as measured by the minimal SPR distance to any rooting of a supertree) when the gene trees are correctly rooted. We compared MRP supertrees using the default parameters (MRP), or seeded with the correct tree (MRP-C) to SPR supertrees using the default parameters (SPR), seeded with an MRP starting tree (SPR–MRP), or seeded with the correct tree (SPR-C). The lower panels compare the mean error of the MRP supertree to SPR supertrees when the gene tree roots are unknown, using our balanced accuracy-based simple unrooted comparison without and with an MRP seed tree (SPR-SU and SPR–MRP-SU, respectively).
