SPR-Aquificae | SPR-Aquificae-Rooting | SPR–MRP | SPR–MRP-Rooting | |
SPR-Aquificae | 0 | 10 | 34 | 33 |
SPR-Aquificae-Rooting | 10 | 0 | 27 | 25 |
SPR–MRP | 34 | 27 | 0 | 2 |
SPR–MRP-Rooting | 33 | 25 | 2 | 0 |
Notes: We compared the minimal SPR distance between any rooting of the SPR supertree constructed from the 40 largest trees with a monophyletic Aquificae group (40-Aquificae), the SPR supertrees constructed using the MRP supertree (SPR–MRP) or SPR-Aquificae supertree (SPR-Aquificae), and the SPR supertrees constructed by only rooting the gene trees using the MRP supertree (SPR–MRP-Rooting) or SPR-Aquificae tree (SPR-Aquificae-Rooting) and building a greedy addition supertree.
