Distance from a root

Hello,
is there a simple option to call to obtain the distance of each node from
a "root" node?
Cheers,
Andrea

Not yet. Graph-tool is being extensively redesigned as fully-fledged
python module (as opposed to a stand-alone command line tool) -- see the
no-conversions branch in git for more details. This will allow more
finely tuned calculations such as this. But a release will take some
time, since I'm quite busy with other things at the moment.

Cheers,
Tiago
