Description | This program generates k random phylogenetic trees with n leaves (i.e., species, taxa) and an average branch length l using the random tree generation procedure described by Kuhner and Felsenstein (1994). The branch lengths of trees are computed using an exponential distribution. The branch lengths are multiplied by 1+ax, where the variable x is obtained from an exponential distribution (P(x>k) = exp(-k)), and the constant a is a tuning factor for the deviation intensity (as in Guindon and Gascuel (2002), the value of a is fixed to 0.8). The random trees generated by this procedure have depth of O(log (n)). | |
