[GRASSLIST:305] i.gensigset and subgroup setting..

[Luca Casagrande]

Hi guys!
I have imported an ECW into an RGB layer and now I wanna do some 
reclassification using i.gensigset and i.smap.
I don't understand how set group and subgroup for this image (both required 
for i.gensiget): I grouped the R,G,B but which subgroup should I set? 

Thx
Luca
