Hi Guru,

Thanks for getting back to me so quickly!

I'll give that a try and let you know how it goes. If this is the
problem, perhaps the instructions could be updated under the took
because the current directions give a different formatting of the
tree. It is a little counter- intuitive to have to put parentheses
around one species. Do you think it will be the same for four species?
(That I put parentheses around just hg18)

Thanks again!!

Best,
Melissa

Hi Melissa,

Looks like Hyphy doesn't like the way you specified your phylogenetic tree. I tried running the tool on your test dataset with the tree defined as ((hg18),panTro2) and it ran just fine! Please give it a shot and let me know if the problem persists.You can find a working example of the same here:http://main.g2.bx.psu.edu/u/guru/h/imported-melissa-test-history  (see history item #8)

Thanks,Guru.

Hi there,

I am trying to use the tool Branch Lengths Estimation under the Evolution heading.

I have a pairwise alignment - (hg18,panTro2), but when I try to run the tool, using the HKY85 model on my FASTA formatted alignment, I get nothing in the output.

It doesn't give an error, but instead gives:

143: Branch Lengths on data 120

empty, format: tabular, database:hg18Info: Single Alignment Analyses

Any ideas?

Thanks!!Melissa
