Emmanuel,
Here are some ideas
Is the region correct? That is, do these coordinates occur in your region
(check extents and resolution using g.region -gp or directly from the menu)?
Are the end of line/carriage return characters correct? You are on a Linux
system which ought to produce the correct ones, but it's worth checking.
Try a different field separator. Try a comma.
Change your column names. Using "nul" and/or "val" could be problematic

When I had a similar problem, I ended up using csv file from a
spreadsheet as the input file.

Hi,
for me (GRASS 6.3cvs) the import of your test data works, the syntax is
correct. Maybe you need to check your test.txt for <space> values in
your
columns etc?

Hi all,
I'm unable to input text file in GRASS using v.in.ascii.
I'm (trying) working on GRASS 6.2.1 under Ubuntu Fiesty
I have a text file (test.txt) which containing:
1|3.5|43.6|2.3
2|3.55|43.605|1.2
3|3.51|43.621|-2.3
4|3.485|43.704|56.1
5|3.498|43.5|7.1058
I would like to import it in a new layer with the following command:
cat test.txt | v.in.ascii out=test columns='nul int, x double, y
double, val double' fs="|" x=2 y=3 z=0
and the outputs of that command is:
Maximum input row length: 20
Maximum number of columns: 4
Minimum number of columns: 4
column: 1 type: integer
column: 2 type: double
column: 3 type: double
column: 4 type: double
Building topology ...
0 primitives registered 0 areas built 0 isles built
Attaching islands:
Attaching centroids: Topology was built.
Number of nodes : 0
Number of primitives: 0
Number of points : 0
Number of lines : 0
Number of boundaries: 0
Number of centroids : 0
Number of areas : 0
Number of isles : 0
So no points are imported in the layer.
I turn around that problem wich normally should work, as what I raed
everywhere, but not for me !!
Regards
E. POIZOT

Hi,
I check for spaces on columns, misllaneous character, etc. The text file
is clean.
I also check the bounadries of my region settings and it's ok, the
points are inside it.
I just produced a CSV file from a spreadsheet, and still not work.
How to know what happend durin v.in.ascii execution (debug or a log file) ?
Regards

Hi all,
I found the problem, now it's working.
I think it was a problem of rights at the group level. I explain:
I wanted to work on a directory located on a server (Debian).
I did create without problems the GRASS database and the mapset.
But using the v.in.ascii command in debug mode, I discovered that there
was a problem with a .tmp file which couldn't be deleted.
I dedided then to move the entire directory on the local machine on
which I was running GRASS and then everything becomes ok.
Thanks all for your help.
As I'm starting using GRASS more deeply now, I guess we will have
occasions to talk again :)
Regards
EP
