[GRASS-user] Problem with v.class.mIR

[Moritz Lennert]

Sorry for ignoring you up to now, just to much on the platter right now.

Would it be feasible for you to make the data available, privately if 
necessary ? The easiest (and lightest) would be just the csv output of 
v.db.select on the training_map and the segments_maps.
