SPR–MRP-Rooting | 52,867 | SPR-Aquificae-Rooting | 53,534 |
SPR–MRP | 52,896 | SPR-Aquificae | 54,488 |
MRP | 52,896 | 40-Aquificae | 55,570 |
SPR-Aquificae-Rooting | 58,539 | SPR–MRP-Rooting | 58,023 |
SPR-Aquificae | 59,561 | SPR–MRP | 58,057 |
40-Aquificae | 60,611 | MRP | 58,057 |
Notes: Six different construction methods were compared: The MRP supertree (MRP), 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. Each supertree was compared with the MRP rooted gene trees or SPR-Aquificae rooted gene trees with the SPR distance.
