I have a star-tree (a non-tree - it is just once central node with x number of tips) in .newick with no branch lengths, and a simulated DNA alignment in .fasta format that I would like to use to add branch lengths to the tree.
I do not want to test the fit of the alignment to the tree, or look for better trees, I just want to obtain branch lengths.
Does anyone know a simple way to do this?
Basically I have simulated DNA evolution over the star-tree to explore branch-attraction events. In making a figure to show what I have done, I want to add proper branch lengths to the star tree to show that they are not all uniform in length (gamma distribution was involved, so there should be a distribution of lengths).
Thank you for your help.
