[GRASS-user] i.smap fails because it can't find subgroup (?)

[Nikos Alexandris]

I successfully run i.smap with GRASS6.2.3 (from Ubuntu repositories).
Still, I get the same error message in GRASS6.3.cvs!

The group, subgroup and the signature files/directories are there and
the REF's are not empty.
