Cannot handle unrooted input trees #3

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Say tou want to use a starting tree that you have computed with e.g. fastphylo. 
If you use option -g to input the start tree, you will get an error message 
telling you that the input is not a binary tree. This is because unrooted trees 
typically have outdegree 3 at the "top". 

What is the expected output? What do you see instead?
Options:
1. To root the tree arbitrarily.
2. To find a root that minimizes the number of duplications.
3. To ignore the first trinary node and create two nodes that arbitrarily 
connect and roots the three subtrees.
