Hello,What can I do if the following error occurs when I process MODIS L1B data using OCSSW L2Gen code:
reading Thuillier_F0.dat
-W- /home/dshea/focs/oel_hdf4/libl1/l1_hmodis_hdf.c:400: Cannot open file:
Error reading ; please specify a valid geolocation file.

Hi,

If you can provide more details we can look into it further? Here is an older post that might help: https://oceancolor.gsfc.nasa.gov/forum/oceancolor/topic_show.pl?pid=39090;hl=please%20specify%20valid%20geolocation%20file

l2gen takes L1B and geo files as input. See https://seadas.gsfc.nasa.gov/help-8.2.0/processors/ProcessL2gen.html#COMMAND_LINE_HELP

It seems that l2gen can't find the geo file that goes with your L1B file. It might be helpful that you share the command line or the par file for l2gen.
