[Bioperl-l] nucleotide changes along tree

[Nicholas Price]

Hi

I have  three nucleotide sequences from human, chimp and Orangutan and
the corresponding tree.I want align the sequences and for each column
in the alignment where there are substitutions, I want to infer on
which branches the changes occurred using a maximum likelihood method.
Is there a way to do this in Bioperl??

thank you

Nicholas
