HI 

Ive run pplacer on my sequences and when i am converting my tree using the following command: 

guppy fat --node-numbers --point-mass --pp -o query.hug_tol.clean.align.phyloxml query.hug_tol.clean.align.jplace

I get this error :

Uncaught exception: Failure("query.hug_tol.clean.align.jplace has no placements!")
