Robinson-Foulds distance analysis of trees. The distances were computed from trees of the RAG1 study (see below). For each world length between 1 and 10, a signature tree was computed and compared to the NJ, ML and random trees. For comparison of random trees and signature trees, 100 random trees were built. In this latter case, the dT is approximately 86 (the maximum value possible with this number of species). As a reference, dT between the NJ and ML trees is plotted as dashed line. The dT of the n-/(n+1)-letter word trees was computed for the Euclidean and χ2 metrics.
