Hi,

I have a MCC tree of a discrete phylogeographic diffusion model. It is
a very large tree with 200 + taxa.
For some reason, states (locations) are missing from some of the
branches and internal nodes.
Is this because branches or nodes in the the MCC must have states with
a set that has a large enough posterior probability? Can this
threshold be adjusted in TreeAnnotator?

Thanks, Matthew

Dear Matthew,
The missing states are probably due to the "Posterior probability limit" setting in TreeAnnotator, which has a default of 0.5. With this setting, all nodes with posterior probability < 0.5 will not be annotated. Simply set this to 0 to obtain all annotations -- this will be the default in the upcoming BEAST release.
Kind regards,
Philippe

Hi Matthew,

Yes, you need to change in TreeAnnotator the box "posterior probability limit" from the default value (0.5) to 0. That should do it. Good luck.
