[Bioperl-l] Taxonomy hierarchy extraction

[George Heller]

Hi all,
   
  Can anyone point me to some example that uses the get_all_Descendents method from Bio::DB::Taxonomy? I am a newbie at this, and I am not quite sure how to implement it. 
   
  Thanks.

Well, you'll use Bio::DB::Taxonomy presumably, and each_Descendent in
some kind of looping structure. Most easily a recursing sub.

If you happen to code up something neat and efficient, why not share it 
with us and we could add it to the Taxonomy module(s).
