Hi Sergio,
indeed I've looked into it and I can get a network using vmtk 1.0.0 (which
doesn't
get stuck when it can't trace a line - it simply skips it).
I just need some more time for understanding why I don't get a few of the
branches,
I'll keep you posted.
Thanks for the patience and for the feedback
Luca
