Bio::TreeIO, Root-tip branch lengths

[Jun Inoue-2]

Dear All,

I just started to learn BioPerl for phylogenetics.
Usually I am using perl v5.10.0 on my Mac OS 10.5.8.
I would like to ask you a hint to calculate the Branch lengths
from root to tip for all species in NEWICK TREE format.

Please see the following web site.
I am explaining what I want to do and
showing my easy script (not completed).

Thank you for your help.

Best,
Jun Inoue

Hi Jun,

Some hints: incorporate

@leaves = $tree->get_leaf_nodes;

and

use Bio::Tree::TreeFunctionsI;
$distance = $tree->distance( $node_a, $node_b );

cheers, Mark
