It might be helpful if you could take a screenshot of your geolocate_viirs GUI and post it here. If you provide the name of the VIIRS L1A file, we can try to reproduce the error and figure out to help you solve the problem. BTW, if you don't want to do geolocate_viirs yourself, VIIRS GEO files can b...

From your 1st screenshot, it seems that you need to set up your ~/.netrc file.

There is an instruction regarding "Create a .netrc file" on this page -- https://oceancolor.gsfc.nasa.gov/data/download_methods/

I tested l2gen (V2021.2) on A2013067094500.L1B_LAC, and it seems to work fine.

What version of SeaDAS and what tag of OCSSW were you using when everything worked fine?

What did you do when you "updated SeaDAS"?

Not sure if these are what you are looking for

It’s a calibration issue. We don’t have gains for L7 (so unity values are used). As a result, this scene has negative rhos. We do not provide the calibration adjustments that would be necessary to get valid retrievals, but you can see if this paper helps: https://doi.org/10.3390/rs10091337 Attached ...

Are you trying to do l2gen on Sentinel 2 data?

With l2gen, you can define the area of interest in the processing tab, but I don't think you can set resolution for data other than modis.

In SeaDAS 7, modis_GEO.py and getanc.py are in $OCSSWROOT/scripts, and anc_utils.py is in $OCSSWROOT/scripts/modules. In SeaDAS 8, modis_GEO and getanc are in $OCSSWROOT/bin, anc_utils.py is in $OCSSWROOT/bin/seadasutils. It seems to me you are running modis_GEO.py in SeaDAS 7 on command line. I won...
