[GRASS-user] i.class and signature file GRASS 64

[Carmine Massarelli]

Yesterday I was using it with i.gensig with training area rasterized, 
but the result was that all class in the signature file were not created 
(nothing else in the message windows). I thought that it depended from 
the relative significative number of the selected pixels.
Then I tried with i.class. The procedure was this: first d.mon to open 
new monitor, second i.class, but it was not possible to visualize any 
map in the new monitor. So i though that the problem was the same, and 
linked to the signature file.
Could you help me to explain the exact procedure or if i need of any 
other component? I have ubuntu 14.04 with gnome.
there are rules to respect to create class in the signature file with 
i.gensig?
Thank you very much
