This is a note of caution about re-rooting trees in FigTree.

If you have annotated branches in FigTree (for example bootstrap  
values, posterior probabilities) then after re-rooting, these may  
appear next to the wrong node (i.e., the child of the the node that  
was formerly a parent). At the moment, there is not an obvious way to  
fix this. I would suggest turning off such labels and then perhaps re-
annotating by hand. Branch lengths and node ages should be correct.

A more obvious point is that node height HPDs and mean values provided  
by TreeAnnotator (in the BEAST package) will be meaningless if the  
tree is re-rooted.

Thanks,
Andrew
