[Bioperl-l] How to Remove root node from a tree, ???

[kenzy ken]

Hi all:
    I write a script which used the Bio::Tree module. I want to remove some
nodes from the tree, so I used "$tree->remove_Node($node_object);method . It
works ok, but when I remove root node, problem happened. It seens that this
method can not remove root node, so ,if you guys have any idea about how to
remove the root ,it will be very appreciated.
