You probably have to set the region extent. Something like:
g.region rast=temp.1 -p

also I got six raster raster map temp.1 temp.2 and ...temp.6

That's because multi-dimensional datasets are split once imported in
GRASS' database. You can view/process each "band" separately. If you
need to use a module which requires the data to be grouped, you have to
use "i.group" to... well, group the "bands".
