dqt	an (n choose 4) x n (or n+1) matrix of form output by quartetTableDominant; (Note: If present, the n+1th column of dqt is ignored)
method	tree building function (e.g., fastme.bal, nj)

Details

This function is a wrapper which runs quartetDist and then builds a tree.

Value

an unrooted metric tree of type phylo. Edge lengths are not in interpretable units
