Clinical isolates (group I C. canimorsus), group II C. canimorsus isolates and C. cynodegmi isolates separately formed three clades in the consensual phylogeny and these three clades were supported by a majority of tree topologies (677, 729, and 686 respectively).
This tree contains only those partitions which are present in a majority of the trees in a neighborhood.
(CW1) Maj+ P) displays all of the majority plenary splits in P. (CW2) Maj+ P) is compatible with each majority partial split in P. (CW3) Each split in Maj+(P) is compatible with a majority of the trees in P. (CW4) Every plenary split in Maj+(P) extends at least one input tree full split.
The fast-growing toi and the tavahi constitute a majority of the tree cover on ʿEua.
This will provide a less resolved species tree in which only dichotomies supported by a majority of the gene trees are shown.
The RF distance to the true tree is often decreased by including splits contradicted by a majority of the input trees (i.e., skipping the last step of the algorithm, denoted by ).
Due to the asymmetric distances, MRC and MRP may favor relationships contradicting a majority of the input trees [ 25].
For a majority of the phylogenetic trees the topologies in the NJ and ML analysis are in agreement (see Additional files 1 and 2).
We choose f greater than 1 2, because (i) it conveys confidence that a majority of the input trees support the f-frequent subtree, and (ii) it ensures uniqueness: on a given set of leaves, there can be at most one f-frequent subtree.
