Dear Sunanda,
You need to make the GEO files with modis_GEO.py.

Dear Norman
Thank you for reverting. I tried OCSSW>MODIS_GEO tool for GEO files but when we enter L1A_LAC file as a input file the output file automatically is named similar to the original file name with extension .GEO, then only the Run button gets activated. So even if I am specifying a separate file name, the process is not executing stating an error message failed execution exit code error. I tried for few other files it did work but for few specified dates it isn't executing. Is there any alternative method for that?
Regards
Sunanda

If you wish to have more control over the process, you will probably want to use the programs from a terminal window and not via the SeaDAS GUI.
For details on how, see the
SeaDAS help pages, specifically
those for OCSSW.

Dear Sean Thank you for replying. If I want to download data from the following website {{//oceandata.sci.gsfc.nasa.gov/MODIS-Aqua/L1/2008/358/}} how can I understand from the file name which is of Persian Gulf. Kindly revert.RegardsSunanda

You cannot. If you want to find the files for a given geographic ___location, you need to use the
L1/L2 browser or
Earthdata Search.

Ok. Thank you. The problem with GEO files which I was facing was that the files would work only if accessed through Downloads folder path, I was creating a separate folder for separate files in order to avoid confusion. So now my question is there any option to create a separate workspace for the same, so it becomes easier to access different date files.

You have the option to do whatever you want. The scripts do not care where the files are, so long as they are accessible to it.
If the input files are provided without a full path, the code assumes the path to the files is it's working directory. If you provide a full path it will use that.
