[Bioperl-l] Checking a tree input

[Jason Stajich]

It depends on what format the bootstraps are stored in - are they as internal node labels or encoded in the ID string or encoded in the length of the branches?

Because there isn't an explicit format - there are variants of it for newick -  you can move them automatically passing in '-bootstrap_style' => 'traditional')  when initializating the parser.
or you can move them explicitly 

copy them from ID to boostrap slot in the objects after you have created it.
for my $node ( grep { ! $_->is_Leaf } $tree->get_nodes ) {
 $node->bootstrap($node->id);
}

Or you can use the connivence function which does the same thing.
$tree->move_id_to_bootstrap

Presumably these internal node IDs will be empty when there is no bootstrap so you can check them after the fact for your other use case when there are no boostraps.
