hello
I am facing troubles in getting the data processing options in GUI of seadas. The l1gen and l2gen options appears but does not open. I have used this code to install all the bundles and for ocm1 and modis
$ ./install_ocssw.py --local=$HOME/seadas_downloads -b v7.4 --aqua
I have built all the third party libraries too.
If possible can I also know the command line steps for l2gen for level 2 data processing

If you install OCSSW via the command line then you also need to configure the GUI with the OCSSW directory.  To do this just edit the file in your SeaDAS directory "[SEADAS_DIR]/config/seadas.config" and set the following line:

seadas.ocssw.root = [OCSSW_DIR]

Then launch the SeaDAS GUI and the processors will be accessible to the GUI.

Here's a very simple example of processing a MODIS level 1A file (A2010283180500.L1A_LAC) through l2gen:

1. Make a geofile (A2010283180500.GEO):
% modis_GEO.py A2010283180500.L1A_LAC

2. Make a level-1B file (A2010283180500.L1B_LAC):
% modis_L1B.py A2010283180500.L1A_LAC A2010283180500.GEO

3. Make a level-2 OC file (A2010283180500.L2_LAC_OC):
% l2gen ifile=A2010283180500.L1B_LAC geofile=A2010283180500.GEO ofile=A2010283180500.L2_LAC_OC
