Dear Dan,

If I recall correctly, when I used the hclust function in R couple years ago, it did not return ultrametric trees (tips are aligned), which should not be the case based on the UPGMA algorithm. If this is still the case, I would use the "phangorn" R package and it's upgma() function.

Cheers,

Aki

Hi,

 

I wish to perform cluster analysis (e.g., UPGMA) on a TPS file.  What are the options I have, how do I do it and which softwares/packages can execute this task?

Thank,

Dan
