Hi, I was trying some simple methods for the Newick tree. I did the following, >t = Bio::Newick.new("(A,(B,C),D)") >t.tree.nodes =>[(Node:43c98a8), (Node:"A"), (Node:"B"), (Node:"D"), (Node:43c91f0), (Node:"C")] > t.tree.number_of_nodes => 6 Am I doing something wrong? I am using bioruby version 1.2.1 in ruby 1.8. Any suggestions are welcome. Cheers, Kaustubh
