I am also encountering this problem. Any solutions?

[ladavid]

Can you confirm the species tree is rooted and the root branch has a branch length? Best wishes, - Lawrence

Hi Lawrence. Thanks for reaching out. I figured out for my tree that some of my programs were not including the root properly in the .nwk file after rooting. The solution to get them to run was to enclose the tree in parentheses and add a :0 branch length for the root. Without doing this, there was an odd number of colons in the Newick file and multitree.py never got to colon_count == 1 to calculate the root distance.
