Ancestral state reconstruction?

[Ivan Adzhubey]

Hi,

I have an alignment (FASTA) and a tree (Newick). Is there any way to reconstruct states for all (internal) nodes? I do not need anything fancy, just maximum parsimony method would suffice but I would prefer to stay within Bio::Phylo, not introducing any dependencies to other software. I can do Fitch's algorithm in DendroPy (Python) but I can't find anything like this among Bio::Phylo methods.

Thanks,
Ivan
