In MSCquartets: Analyzing Gene Tree Quartets under the Multi-Species Coalescent

Compute the Weighted Quartet Distance Supertree

Description

Apply the Weighted Quartet Distance Supertree method of \insertCiteYR19;textualMSCquartets to a collection of quartets on n taxa together with internal quartet branch lengths, specified by a table.

Usage

WQDS(dqt, method = fastme.bal)

Arguments

dqt	an (n choose 4) x n+1) matrix of form output by quartetTableDominant
method	a distance-based tree building function (e.g., fastme.bal, NJ, etc.)

Details

This function is a wrapper which runs quartetWeightedDist, builds a tree, and then adjusts edge lengths with WQDSAdjustLengths.

Value

an unrooted metric tree, of type phylo
