Hi Antonio
Looks like mert thinks you've got sparse features in your run2.features.dat
file.
Could you grep for the underscore ("_") character in this file? If that doesn't
turn up anything then maybe you could let me look at your features file? If
it's too big to post to the list then send it to me off-line,
cheers - Barry
