  1. ASTRAL-III failed due to running beyond the maximum wall clock time of 48 h; SVDquartets failed due to segmentation faults; RAxML failed due to running out of memory; NJMerge failed due to being unable to find a legal siblinghood. Note that NJMerge is described by the input set \({\mathcal {T}}\) of constraint trees and input distance matrix D; see “Performance study” section for more information on the notation
