I had forgotten that geolocation alters L1A files.    It would be useful to know if the altered files are reproducible. The majority of issues I have seen for getanc.py were either network issues or conflicts when multiple getanc.py were run (e.g., a  batch process appeared to hang so...

Before going further, we should verify that your file is the same as one that works:$ shasum A2017184170500.L1A_LACa84dc3904273d412380eb4d478099bfcc058e3e6  A2017184170500.L1A_LACOnce you have run getanc.py, it seems to check the database before it goes to "Determining pass start and end t...

Adding the missing bands to an existing L2 file would be faster than running an updated l2gen.  In general, it is probably better to minimize use of trivial algorithms in  l2gen and do more trivial processing separately as you propose. Tracking down what looks like a glitch in l2gen could,...

Do all the added ancillary variables have entries in $OCSSWROOT/run/data/common/product.xml?   It might help to give the full l2gen command or at least a list of the added variables.  You could try creating level-2 files for one variable at a time to see if the issue is associated wit...

update_luts.py is fine in SeaDAS 7.4 here. Check that your scripts are really on branch v7.4: $ cd $OCSSWROOT/run/scripts$ git statusOn branch v7.4Your branch is up-to-date with 'origin/v7.4'.nothing to commit, working tree cleanProblems like the one you found can occur when someone forgets ...

There is already very good advice from Danny Knowles, but I wanted to mention another approach.  If you have the OCSSW processing system you can use l3bindump with the level-3 binned data to generate ASCII files with binned data values.  You can then use the data with one of the many full-...

Another user here mentioned that he had not received the email notification.  He did look in the junk and quarantine folders.  He is, however, able to check status online.

The SeaDAS 7 GUI is very complex, so takes some time to learn.   Assuming that you are interested in statistics for surface (satellite) chlor_a, you aren't trying to do anything unusual, so you are probably missing a small step that experienced users do without even thinking.  The...
