[GRASS-user] i.spectral and gnuplot

[Stuart Edwards]

Hamish, Francesco

After fearing for my sanity, I think I may have found the problem.  
The script in Lorenzo's binary distribution is not the same as the  
one that you pointed me to in spite of identical headers.  Attached  
'i.spectral' is from the distribution, 'i.spectral2' is the script at
  <http://freegis.org/cgi-bin/viewcvs.cgi/*checkout*/grass6/scripts/ 
i.spectral/i.spectral?rev=HEAD&content-type=text/plain>
The differences start at about line 51.

Tomorrow I'll have a crack at this again using the correct version!   
Gnuplot does open on command from the shell and GRASS_GNUPLOT = /sw/ 
bin/gnuplot.

Regards

Stuart
