hi all,
i am having problems with running nviz..i've read here in the list that there is a problem with tcl8.4 version (used by grass) because nviz runs better in a tcl8.3 environment...i have tcl8.3 installed in my pc..how do i proceed in this case? does someone can help me giving step by step instructions?
i am using a debian/knoppix based distro...the ultimate version (but not with the newest linux kernell)
thanks in advance
samuel

I added the header at the beginning of w001001.adf file in this way:

ncols 2492
nrows 2272
xllcorner 4675800
yllcorner 1550000
cellsize 100
NODATA_value -9999

I add part of the file because I'm not sure if it is data file.

But the output message now say:

r.in.arc input=/home/Documenti/AAA-verificare/DTM_nuovo/dtm/w001001x.adf
output=w001001 type=CELL mult=1.0 0%ERROR: data conversion failed at row 1,
col 1

Where do I wrong?

Thank you again
