[Bioperl-l] module Bio::TreeIO

[Roy Chaudhuri]

Hi,

I can see why you were confused by the boot.phylo docs, it's not very 
clear, but it is resampling columns from an alignment.

I've uploaded a script to GitHub which does a BioPerl-based bootstrap 
analysis, maybe it will be useful for you.

However, I would note that BioPerl is certainly not the most efficient 
way of doing this, and neighbor-joining is not the most robust method of 
constructing a tree (more sophisticated approaches are available in 
programs such as RAxML and MrBayes).

You're right about the assess_bootstrap docs. You could post this as an 
issue on GitHub (or even better, fix it and submit a pull request):

Cheers,
Roy.
