Hi all,

I've recently finished a tip-dating analysis (see
https://www.mail-archive.com/r-sig-phylo@r-project.org/msg04659.html) and
I'm now trying to import the trees from the posterior (input.nex.run1.t,
etc.) into R for some comparative analyses.

Using read.nexus, I was able to successfully import the trees, but for some
reason the branch lengths seem to be off.
The branch lengths for the consensus tree (from sumt) appear to import into
R fine (with the root at about 210 Ma), but the posterior trees seem to
have root ages ranging from 43 to 147.

Am I missing something in my MrBayes nexus file/analysis, which is causing
the branch lengths to be off in the output file (I was under the impression
branch lengths are by default printed with the trees)?
Or is there a different (better) way to import them into R?

Thanks in advance,
