Am trying to run an idl script but am encoutering a problem with the location of the LUTS. I wanted to use the 02-standard_chl. lut but the program indicates that the file is not found. Has anyone encountered a similar problem? If so give me the link to the solution.

Idl script is:

  load, 'final_smi.hdf'
  display, smin=0.00, smax=32.0, stype='LOG'
  loadpal, '$HOME/seadas/seadas/config/color_luts/standard/02-standard_chl.lut'
  loadgp, color=1, red=61, green=43, blue=25
  loadgp, color=2, red=137, green=114, blue=48
  landmask, color=1
  coast,color=3,/rivers  &  coast,color=2,/coasts  &  grid,grdcol=7
  tvlct,r,g,b,/get
  r[195]=0  &  g[195]=0  &  b[195]=0
  tvlct,r,g,b
  out, 'final_smi.png', /cbar

Error is:

Please help

Have you checked to see if the path to the lut is correct?  $HOME/seadas/seadas/config/color_luts/standard/02-standard_chl.lut seems suspicious.
You may try $SEADAS/config/color_luts/standard/02-standard_chl.lut

The color palettes distributed with SeaDAS are located under the SeaDAS root directory
(the environment variable $SEADAS points to this directory) in the config/color_luts
subdirectory.  If loadpal does not find the file specified, it tries to find it under the idl
resources tree.  So, the path is still not correct.  

what does the following (entered on a command line) return?
ls $SEADAS/config/color_luts/standard/

BTW, it might be as simple as entering only 1 'standard' subdirectory.  The line suggests you have 2:
$SEADAS/config/color_luts/standard/standard/02-standard_chl.lut

Dear Sean,

Thanks so much Sean. The file can now be located but I get an error in the increment range. when I check the default setting I see that the default is 1 but my scripts shows 2. where can I change these setting?

Jane,

I *think* the issue may be with the colorbar.
Try adding an explicit color bar setting prior to the out command, where you define the increment.
