Protein Based Phylogeny Trees

This web page was produced as an assignment for Genetics 677, an undergraduate course at University of Wisconsin: Madison. 

Figure 1 (Left 1,2,3,4,5,6).  A phylogenetic tree of the protein homologs. The branchs are represented in a cladogram, which ignores the branch length. The red numbers are the branch support values (x100 to get percent).
Used: Robust Phylogenetic Analysis For The Non-Specialist to make phylogenetic trees using the one click program.


    The program Robust Phylogenetic Analysis For The Non-Specialist  allows one to run a nice analysis  for protein sequence homologs and DNA sequence homologs.  However, the DNA sequence homologs are often times too long for the program. In addition, formatting can be often difficult to do, especially if you copy and paste your sequences into the program. In addition, it did not like the files I formatted and tried to upload even when I used the Fasta files. So, I have determined that it can be a touchy program especially when dealing with DNA sequences instead of protein sequences. I want to use the program to see if the phylogenetic tress would differ depending on the type of sequence used.

   This is a really simple program and produces a simple result. One cannot edit the tree as well as with Robust Phylogenetic Analysis For The Non-Specialist, but it is a simple program that only takes the protein sequences input by the user, processes for 2 minutes, and outputs a quick and simple tree.
