Hi folks, I generated a quick chronogram in TreeFinder (attached) for an exploratory analysis in R. The tree appeared fine in the Treefinder plot window, but the branch length notation does not appear to be compatible with R plotting for a chronogram.
The basal divergence time is 33.9 MYA (which appears in the Newick file), but FigTree is telling me the base is something around 22. Has anyone else encountered the problem with TreeFinder chronograms? Does anybody have a suggestion for how to rescale? I'd prefer to use this tree rather than simply make the original unrooted tree ultrametric. Thanks! ~John John S. S.
