Hello xuanyang,

Find the statement of both the file below.
I redownloaded the 2023 file and the file you wanted me to download

(base) Euricos-iMac:bin gulfcarbon$ /Users/gulfcarbon/ocssw/bin/obpg_file_type /Users/gulfcarbon/Downloads/A2022023192500.L1A_LAC
A2022023192500.L1A_LAC: unknown: unknown

A2010283180500.L1A_LAC: unknown: unknown

I took a random file and did multilevel_processing and it executed although could not select the OC suite even after writing it in par file. It is in the attachement. but I opened with obpg_file_type, the result is
(base) Euricos-iMac:bin gulfcarbon$ /Users/gulfcarbon/ocssw/bin/obpg_file_type /Users/gulfcarbon/Downloads/MODIS/2022/L1A/A2022241193000.L1A_LAC
A2022241193000.L1A_LAC: unknown: unknown
I tried another system of my lab but the result came same.

Hello gnwii,

I did as you said. I got
(base) Euricos-iMac:L1A gulfcarbon$ file A2022241193000.L1A_LAC
A2022241193000.L1A_LAC: Hierarchical Data Format (version 4) data

I have saved the OCDATAROOT and the installed mission is now ['aqua']. Yet, I am getting same error. I also tried the same method of multilevel processing in another system of my lab. The result came same. Is it something with the installation process?

seadas_info is supposed to give us the info of your OCSSW tag like this --
OCSSWROOT=/Users/*/ocssw
OCDATAROOT=/Users/*/ocssw/share
l2gen version: msl12 9.6.0-V2023.1 (Apr 4 2023 11:28:21)
l2bin version: 7.0.4
l3bin version: 5.13
l3mapgen version: l3mapgen 2.3.0-V2023.1 (Apr 4 2023 11:27:05)
Installed Missions: ['aqua', 'terra', 'olil8', 'olil9', 'viirsn', 'viirsj1', 'viirsj2', 'viirsdem']

The error
"Environment {$OCDATAROOT}: Not Installed
l2gen version: -E- /Users/gulfcarbon/ocssw/bin/l2gen: Error parsing input parameters."
makes me think there might be issues with your installation.

I am also puzzled how you can finish the multilevel_processor process on a single L1A file and
1. you didn't get complaint like this --"Warning: Unable to determine a type for file /Users/gulfcarbon/Downloads/MODIS/2022/L1A/A2022023192500.L1A_LAC. It will not be processed."
2. you are able to do geo, level 1b and l2gen without the "aqua" mission installed. Can you, in SeaDAS, open the L2 file created by multilevel_processor, and see if you get a reasonable chlor_a image?

Can you do ?

Did you install Science Processors (OCSSW) by GUI or command line? If by GUI, were you able to choose a tag? If by command line, what tag did you give to the --tag option? Could it be possible that you didn't finish the install process?

If you decide to reinstall OCSSW, you can delete /Users/gulfcarbon/ocssw/ and install OCSSW again either by GUI or command line. -- https://seadas.gsfc.nasa.gov/downloads/

If by command line, make sure you command has -- tag 2023.2, and --seadas --modisa like this -- Also add these lines to your .bashrc file --
export OCSSWROOT=[SeaDAS_install_dir]/ocssw
source $OCSSWROOT/OCSSW_bash.env

If by GUI, make sure you choose tag 2023.2, and at least check aqua for missions.

Seems like this line actually worked without uninstalling seadas. I have got the processing started.
source $OCSSWROOT/OCSSW_bash.env.
Thanks to you (and one of my friends). But can you kindly explain why this line was needed.
Also, after processing of few scenes I am getting

and I deleted the scene A2005127192500.L1A_LAC but every 4th or 5th image is show this error. I have enough space. I am also sharing the warning log report.

Thanks a tonne for your help.

multilevel_processor has a little trouble to match an L1A file with the right geo file. The solution is to skip [geo] in parfile (mlp knows to create a geo file if it does not find one). So your parfile text area should look like this:

[main]
ifile=/Users/gulfcarbon/Downloads/new2022l1a.txt
odir=/Users/gulfcarbon/Downloads/MODIS/2022

[level 1b]

Thanks to you (and one of my friends). But can you kindly explain why this line was needed.

[Note: added code </> formatting]

Before retiring I worked in a group that did many ocean colour workshops. We found it very helpful to spend the first 2 afternoon of a 2-week workshop introducing the POSIX command-line as used in linux and macOS. Students reported they found it helpful with other aspects of their "research" (some of which probably involved recreational activities). There are many good online resources such as https://linuxcommand.org and distro specific manuals. Ubuntu includes some Debian manuals that have sections on command-line basics as well as system administration.

The script sets shell (bash or zsh) variables that are needed by the various programs to find data directories, names of compilers, type of system, path elements used for Python scripts and the OCSSW programs, etc. Many linux programs do something similar, but the OCSSW package is high on the spectrum of complexity because there are many programs that need to work together and because it supports both macOS and linux. This complexity combined with the many different macOS and linux versions means there can be glitches which are easily fixed with basic knowledge of the POSIX command-line.

Thanks a bunch Xuanyang,
processing is going smooth so far. Probably gonna redo the the files which are causing trouble.
Thanks gnwii,
I will look into the link that you shared for linux learning. All this terminal functions are very new to me and I will try to gain knowledge as mush as possible.
