[Bioperl-l] Fitch methode

[Alexandre Miranda]

Hello,

I desperately try to implement the methode Fitch from the library
Bio:Tree:Statistics.

But I cannot understand what kind of parameter I should used for the $key
value : fitch($tree, $key, $node);

Can you please send me a sample of code using that methode ?

thanks for your quick reply.

Best Regards,

Alexandre
