Hi,
Me again with my variogram map.
I tried the next command file:

#
# gstat command file, DEC/Alpha version 2.3.5 (19 July 2001)
# Wed Dec  4 09:39:49 2002
#
data(ff): 'krig.txt', x=2, y=3, v=4;
mask : 'maskascii';
method: semivariogram;
variogram(ff): 'ff.map';

Th result store in 'ff.map' as 0 on every locations.
Where am I wrong ?

Your command file looks fine - Note that your mask map (mask:..) should
be centered around 0 (i.e. the coordinate (0,0) should be at the centre
of the map). If you are using PCRaster I could email you such a map.
Ciao,
Derek
