Hello List,

While following the manual instructions for the variogram maps (page
14), I am in a fix there as I don't get any output maps while running
the gstat on command file. My command file is like this:

data(back): 'sukho_subasc.eas';
method: semivariogram;
variogram(back): 'back.est': 2626.14 Nug(0) + 5126.29 Sph(60.9673);
mask: 'sukho_sub_mask.map';
variogram(back): 'back.map';

My data is in grid format. The program runs well without any errror
messages. As per manual instruction, I expect to get a variogram map but
the 'back.map' contains only the NODATA_VALUE     -9999. May somebody
please clarify me where I am going wrong. 

With regards
Shakil
