Not be able to access grass map

[Malcolm Williamson]

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,
	-Malcolm Williamson
