OCSSW Processors Not Installing - WSL

by nathra » Sat Jun 17, 2023 12:24 pm America/New_York

Hello! I followed the instructions for client-server configuration on Windows: https://seadas.gsfc.nasa.gov/client_server/

I was able to get the OCSSW server running on the Ubuntu distribution (WSL 1). However, when I go to SeaDas and try to click "Install/Update SeaDas Processors", nothing happens (I was previously getting an error that the server was not running but I solved that issue). When I try to then run l2gen, I get a java exception: "execution exception: java.io.IOException: l2gen failed with exit code -1." with the log saying: server ocssw root path: /home/nathra/ocssw/bin
Debugging: par file new path: /mnt/c/Users/16309/seadasClientServerShared/l2gen_par_file4750930658340760266.par
Debugging: new par string:

Debugging: command array: /home/nathra/ocssw/bin/ocssw_runner --ocsswroot /home/nathra/ocssw l2gen par=/mnt/c/Users/16309/seadasClientServerShared/l2gen_par_file4750930658340760266.par
java.io.IOException: Cannot run program "/home/nathra/ocssw/bin/ocssw_runner" (in directory "/mnt/c/Users/16309/seadasClientServerShared"): error=2, No such file or directory

I am assuming I am getting this error because I was unable to install the processors.

Is there a way to manually install the processors or fix the issue within SeaDas? Thank you!

It might be easier to install Docker Desktop for Windows and run SeaDAS Science Processors via the Docker image.

Go to the site -- https://seadas.gsfc.nasa.gov/client_server/

In Section 1, click the "Docker" tab, and follow the instructions.
Skip to Section 4, click the "Docker" tab, and edit the file seadas.properties

And you should be able to install/update SeaDAS processors in SeaDAS GUI

https://seadas.gsfc.nasa.gov/downloads/ has a section for "Manual Installation".

If you have not used Linux command-line tools before, you will find it helpful to spend a few hours with a basic introduction to the linux command-line such as https://linuxcommand.org.
