Hello, I am using SeaDAS 10.0.0 (full installation) on a Linux HPC cluster without root access, with a user‑installed OpenJDK 8, and while gpt -h works correctly, any actual processing (e.g., reprojecting a VIIRS L2 Ocean Color NetCDF file) fails with java.lang.NoClassDefFoundError: org/openide/util...

Dear Sean,

Thank you very much for your helpful answer, as shown in the attached picture, I am curious why the west region seems not affected by patchwork.

Hello, I used l2gen to process MODIS/Aqua L1A data to L2 data, all parameter settings were default, but the L2 PAR data have a lot of  plaids (an example is attached). How can I solve this problem? What's more, the values of our L2 PAR data were about 10 einstein m-2 day-1 less than the L3 PAR data ...
