r.in.ascii

Hi dear GRASS users:

I am having troubles importing files from idrisi, and hereby securing helps from 
you.

I have exported idrisi files using ascii raster format. And then I edited the 
file (deleting the first two lines of projection and zone, so there are six 
lines as the header). After ftp them to GRASS, I ran r.in.ascii. Everything 
looked okay. However, when I tried to display it, it was blank--three or four 
non-sense colorful lines at the top, and elsewhere was just white. I checked the 
file under cellhd directory. It reads:
	 proj:       1
	 zone:       16
	 north:      4386270
	 south:      4351770
	 east:       730110
	 west:       686490
	 cols:       1454
	 rows:       1150
	 e-w resol:  30
	 n-s resol:  30
	 format:     0
	 compressed: 1
	 
Actually it is in UTM 16, and it is within the current region. I am not sure of 
the last sentence. Does it mean that the file is compressed so that GRASS could 
not process it correctly?

I also tried to export from idrisi using binary format, which produces two 
directories--cell and cellhd, each containing one file of the same name. In 
grass I then ran r.support to get a color table for it. However, this time it 
was even worse--I couldn't get the file done.

I am stuck. Could someone give me some hints? Thanks a lot in advance.
