reroot(1) Compute a (new) root for the tree.


reroot [OPTIONS] tree-file


This program reroots the trees in <treefile> on an selected edge.

The default is to output a random rerooting, but you can also choose to give the edge to put the root on, or an outgroup, or even all possible rootings.

Output is written to stdout unless the exhaustive rooting is chosen. Then -o is giving the prefix for filenames to use and the results are written to <prefix>_<n>.tree, where <n> is the node number of the head of the edge.

Warning! In the current implementation all time/length info is lost.
