[Molecular-evolution] estimating branch length - phylip

I am a new user of phylip. I want to scale a phylogenetic tree.

I constructed a max likelihood tree (dnaml) after using seqboot (500
bootstraps) and then performed a consense to get a final tree. The
tree looks fine but ofcourse it does not display branch lengths
(rather it displays bootstrap values).

So I took this tree, used retree to unroot and eliminate the bootstrap
values. I called this "intree". Now when I use the dnaml again with
the user tree option on the "intree" i am consistently getting an
error message which states that there is insufficient memory. I
understand that this problem is due to a badfile format but I don't
understand what could be wrong with my file.

Has anyone come across this. I would greatly appreciate any help. I
have pasted my tree file here just in case someone can spot a problem.

Is there any way to measure branch lengths?


Thanks a ton,
