tree-puzzle - Reconstruction of phylogenetic trees by maximum likelihood SYNOPSIS
tree-puzzle DESCRIPTION
This manual page documents briefly the tree-puzzle command. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page. TREE-PUZZLE is the new name for the program previously known as PUZZLE! tree-puzzle is an interactive console program that implements a fast tree search algorithm, quartet puzzling, that allows analysis of large data sets and automatically assigns estimations of support to each internal branch. TREE-PUZZLE also computes pairwise maximum likelihood distances as well as branch lengths for user specified trees. Branch lengths can also be calculated under the clock-assumption. In addi- tion, TREE-PUZZLE offers a novel method, likelihood mapping, to investigate the support of a hypothesized internal branch without computing an overall tree and to visualize the phylogenetic content of a sequence alignment. There is also a paralellized version tree-ppuzzle available. OPTIONS
There are no options. For usage please look at /usr/share/doc/tree-puzzle/tree-puzzle.pdf. SEE ALSO
phylip(1), treetool(1). tree-ppuzzle(1). This manual page was written by Dr. Guenter Bechly <>, for the Debian GNU/Linux system (but may be used by others). April 20, 2001 TREE-PUZZLE(1)
