Hi, grass users!
I'm a novice in grass world, and got in trouble.
The trouble is that I could not access any map in the mapset.
I can see map files (just see), but whenever I was trying to
access those map files, I got zero values. Of course, I could
access those maps before, but from this afternoon I could not
do anything with the map files.
Please help me. I must do something until Thursday.

Hi, Seugchan
It sounds like your current region is set incorrectly, so that your map
data is not in its "field of vision". Try:
g.region rast=name_of_one_of_your_layers
d.erase
d.rast same_raster_layer_name
The other possibility is that you have a mask turned on. Do a
g.remove MASK
and see if it actually removes anything. This is something that very
experienced GRASS users still get caught on now and then! (I know this
first hand...)
Good luck,
