Can you share the files you tried to do mosaic on?

It seems that the scene wraps the dateline. GeoTIFF gets very confused when the dateline is concerned. You might want to 1) crop the image so it doesn’t contain any data that crosses the dateline before using the reproject feature or 2) use l2bin and then l3mapgen Also, SeaDAS-8.1.0 was released las...

l2gen on Sentinel-2 takes an L1C file (manifest.safe) as input. You need to make sure your manifest.safe is from the directory of S2A_MSIL1C*

MTD_MSIL2A.xml seems to be from a directory of S2A_MSIL2A*, which is an L2 file.

It will be helpful that you share with us what VIIRS L1 file you used to do l2gen, assuming you have the corresponding geo file.

Could you also please share the screenshot of striped rhos product?

Your [SeaDAS_install_dir] should be /Home/seadas-7.5.3, and OCSSW_bash.env should be under /Home/seadas-7.5.3/ocssw ($OCSSWROOT, not [SeaDAS_install_dir])

BTW, SeaDAS-8.1.0 is available. You are welcome to try it: https://seadas.gsfc.nasa.gov/downloads/

It seems that l2gen GUI does not like the space in your "Satellite image" directory. Can you change your directory name "Satellite image" to "Satellite_image" and try again?

Did you forget to attach the error?
