I can run multilevel_Processor with the par file similar to yours and new2022l1a.txt as following. /Users/*/L1A/A2022023192500.L1A_LAC /Users/*/L1A/A2022014193000.L1A_LAC Most likely, your new2022l1a.txt is not plain text.

I downloaded A2002185040500.L1A_LAC and AQUA_MODIS.20020704T040500.GEO.hdf, did modis_L1B, l2gen, l2bin, and l3mapgen. I was able to create AQUA_MODIS.2002070420020704.L3m_Rrs_645.DAY.nc AQUA_MODIS.2002070420020704.L3m_Rrs_859.DAY.nc AQUA_MODIS.2002070420020704.L3m_nLw_645.DAY.nc AQUA_MODIS.20020704...

SeaDAS should be able to visualize L3m/L4m files, but not L3b/L4b files.

Here is a video tutorial of the Basics of SeaDAS 7 -- https://www.youtube.com/watch?v=rSTM1e7tfsg

Tutorial videos on SeaDAS 8 are coming soon...

Check if /home/reema/SEADAS/ocssw/var/viirsn/cal/OPER/VIIRS_NPP_CAL_STATIC_LUT_v3.1.0.13_20220728_obpg.nc exists. If not, do SeaDAS-Toolbox -> Update Luts

Are you using SeaDAS 8.3.0? Could you please do SeaDAS-Toolbox -> Software & System Info, and post the result here?

Also, it will be helpful if you could share the name of your VIIRS SNPP L1A file.

get.finddb() calls status = ancdatabase.check_file(filekey,starttime=self.start) ancdatabase.check_file queries the database with 'select satid from satfiles where filename = "A2022347062000.L1A_subset_LAC"'. Unfortunately, when you did getanc and modis_atteph with -s and -e option, you st...

Edit an l1files.txt with plain text (vi or emacs), like this -- /Users/*/Scenes/MODIS_AQUA/forum/A2023051011000.L1A_LAC /Users/*/Scenes/MODIS_AQUA/forum/A2023131213500.L1A_LAC Edit a par file (mlp-aqua-l2gen.par) like this -- # Sample par file for multilevel_processor.
