Hmmm...

I can't get any my existing subgroups listed when I try the interactive
way!

However it works (almost) when I put everything in a command line:

i.class map=MOD2006NIR group=MOD2006 subgroup=BGRNIR outsig=i.class_TEST

(my problem is that I always get a data error when I try to "analyze" a
region digitised within i.class).
