Figure 1From: A support vector machine based test for incongruence between sets of trees in tree spaceSchematic of how trees are converted to vectors. Numbers on branches in the unrooted tree are branch lengths. In this example, the tree is first converted to either a branch length-based dissimilarity map (matrix of distances between tips) or topological dissimilarity maps (matrix of number of edges between tips). Moving from left to right across rows in one half of a matrix, values are placed into a single column to yield a vector of distances between tips in the tree.Back to article page
