Tree File Formats. FigTree fails to read TREEBASE Nexus trees?


For one example, the molecular phylogeny of primates in this paper is stored in TreeBase:

The tree is available in several formats:

But I cannot get FigTree (version 1.4.0, on a Mac OSX-8 machine) to open any of those file formats.

it says Error: Unknown command “TITLE” in TREES block.

I can open the NEXUS Treefile and edit it by hand, but it seems to me that there should be a way to have FigTree ignore commands that it does not recognize, with a warning that it is doing so, rather than just refusing to open the tree altogether.


1.4.2 loads this tree OK (because it ignores commands that it does not recognize).
