[Bioperl-l] bootstrap values in cladogram

[Jason Stajich]

not sure if the cladogram is printing bootstraps from the internal id or 
the bootstrap function.

See the example code here  http://bioperl.org/wiki/HOWTO:Trees that 
shows how to automatically convert internal IDs to boostrap slots 
basically by using
-internal_node_id => 'bootstrap'
in the TreeIO initialization.

You may want to iterate through the tree and print $node->bootstrap 
where you think it should be so you can verify that it is working too.
