importing raster files from Idrisi4.0 for DOS

[Houxiang Wang GEO Grad 96]

Dear GRASS users:

I am having troubles importing files from idrisi4 for DOS, and hereby securing 
helps from you. I posted the same request two weeks ago, but have not got many 
responses.

1. I exported idrisi4 files using ascii raster format. Then I edited the 
files (deleting the first two lines of projection and zone, so there are six 
lines in the header part). After ftp them to GRASS, I ran r.in.ascii to finally 
get GRASS format raster files. Everything looked okay. However, when I tried to 
display it using d.rast (and p.map), 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 the file is of UTM 16, and it is within the current region. I am not 
sure of the last sentence above. Does it mean that the file is compressed so 
that GRASS could not process it correctly?

2. I also tried to export from idrisi using binary format, which produces two 
directories--cell and cellhd, each of which contains 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.
