dear all,
I have a question when I used the pic funtion, it appeared an error:'phy'
is not rooted and fully dichotomous, I don't understand what's the problem,
the attached file is my phylogenetic information, please check it, I am sorry
to trouble you all, but I really want to solve this
Hi. This is because your tree is not fully dichotomous.
tree-read.nexus(file=tree.nex)
is.binary.tree(tree)
[1] FALSE
You can resolve multifurcations with branches of zero length using
multi2di(), e.g.:
tree-multi2di(tree)
is.binary.tree(tree)
[1] TRUE
Hope this helps. - Liam
