Adding annotation to trees is not possible because of the lack of edge lengths about rotl HOT 4 CLOSED

Hi,

I have the same problem than you, there is no branch length, so I can't see all the nearer species among others.

Dis you find a solution or at least download another tree of life with the branch length.

Thank you

The trees returned by the Open Tree of Life do not have branch lengths. These trees are only intended to show the relationships and do not include a measure of evolutionary distance. You could add arbitrary branch lengths to the trees so they can be plotted with phylobase. The ape package allows you to plot trees with no branch lengths.

this is not an issue with rotl per se, closing.

TimeTree seems to be a better resource for this, but the associated R package timetree hasn't been updated since 2015 and appears to no longer work. Did find the source code here though: https://github.com/cran/timetree

TimeTree also provides a frozen version of a 50k species tree here:
http://www.timetree.org/book

Doesn't take long to read in either:

tr <- ape::read.tree(file = "http://www.timetree.org/public/data/TimetreeOfLife2015.nwk")

Can't seem to find any API documentation for TimeTree, but if I can I'll build it into orthogene (or perhaps its own R package)
