Could you please give SeaDAS 8.4.0 a try? Also install OCSSW (the latest tag is V2023.3) through Docker https://seadas.gsfc.nasa.gov/client_server/

I have Ubuntu 20.04.6 LTS

I can't replicate your error running If the generated GEO file is of the similar size of the GEO file on our site, and can be used for modis_L1B and/or l2gen, you probably can ignore the error message

I got the same error using V2023.2 on linux. Although V2023.2 works on Mac

Try V2022.3 -- it works for me on linux

I tried l2gen on the same file, and got a different result.

I used V2023.2 and clicked "get_ancillary" before "run".

Can you share the filename of one file that produced error?

Can you do on the command line or Software & System Info on GUI and share the result here?

BTW, we now provides Modis Aqua GEO files https://oceandata.sci.gsfc.nasa.gov/directdataaccess/Geo-Location/Aqua-MODIS

Please let us know where you downloaded the terra file from, so we can try to replicate the error. It's also helpful if you can share the output of the following command here seadas_info I did modis_GEO T2023268120000.L1A_LAC with no issues You might want to try again, in case there was connection i...

Here is the fix for the issue of "Percent valid data (0.00) is less than threshold". Please download https://oceandata.sci.gsfc.nasa.gov/ocssw/de200.eos and replace $OCSSWROOT/share/modis/static/de200.eos with it. You should be able to run modis_GEO then. See this -- https://forum.earthdat...

Here are a few options -- 1. You can use get_output_name to get the file name of the command (TARGET_PROGRAM). get_output_name INPUT_FILE TARGET_PROGRAM 2. You can also provide the geofile name and/or output file name modis_GEO L1AFILE -o GEOFILE modis_L1B L1AFILE GEOFILE -o "Output L1B 1KM fil...

You might also want to add a line to /Users/nivas/.seadas8/etc/seadas.properties

Sorry that I forgot to mention that SeaDAS 8.3.10 does have a bug -- when trying to install/update SeaDAS processors through GUI using Docker, the install/update SeaDAS Processors GUI won't show You might want to try installing SeaDAS processors on the docker Terminal /root/ocssw/bin/install_ocssw -...
