l1bgen failed with exit code 1

Hello everyone,

I'm a beginner wth Seadas and with coding and I’m trying to process data from the PACE satellite using SeaDAS, and when I attempt to create the L1B product with the L1bgen tool, I get the following error message:

execution exception: java.io.IOException: l1bgen_generic failed with exit code 1.
Check log for more details.
Loading default parameters from /home/ysaline/SeaDAS/ocssw/share/common/msl12_defaults.par
-E- /home/dshea/ocssw/oel_hdf4/libl1/l1_options.c Line 212: Could not find type for file

Do you have an idea to fix the problem please? Thank you.

Are you trying to do l1bgen on PACE OCI L1A files? What's your input file?

We do provide PACE OCI L1B files here -- https://oceandata.sci.gsfc.nasa.gov/directdataaccess/Level-1B/PACE-OCI/2024/

Hello, I want to determine the amount of benthic light and I plan to work with PACE L1A files and process them using SeaDAS. I downloaded the data using the Python script provided by the web interface, and I wanted to verify that I had downloaded the correct files by opening and processing them in SeaDAS. Here is an example of a file I have processed.

When I return to my terminal, I have the following temporary file. Note that I have checked for updates to OCSSW and the software.

I thing you need to specify, at the very least, both the calibration and geolocation lookup tables:

cal_lut
geo_lut

The l1bgen_generic code does not support PACE OCI. You should simply download the L1B files we distribute, rather that the L1A. However, if you have L1A files, you can run l1bgen_oci on them to generate the L1B...but it'd be faster to download them
