OCSSW Processor - MODIS

by vito609 » Mon Apr 05, 2021 2:09 am America/New_York

Good Day.

I just recently installed SeaDAS and OCSSW processor in VirtualBox Ubuntu.

I tried to to process using modis_GEO.py using code below:

sudo ./modis_GEO.py ifile="/home/torres609/Downloads/MOD00.P2009023.0545_1.PDS"

However, I got an error of:
ERROR: The /home/torres609/ocssw/share/modisdirectory does not exist.

Do I need to install or download additional files? Or do I need to redirect something.

Thank you.

When you install_ocssw, did you use the option --modisa to install MODIS Aqua files? For more information on options, you can run install_ocssw -h.

Also, I assume you installed SeaDAS-7.5.3, for SeaDAS OCSSW processing on Windows is not yet supported in SeaDAS 8.0.0, but is coming soon. Here is more info:

BTW, it would be --modisa for MODIS-Aqua (and --modist for MODIS-Terra, --aqua would get you Aquarius, yeah confusing :( )

Thank you. I'll try to run the installer again.

Alternatively, when I tried to install the processor using SeaDAS GUI I got this error:

##

Check log for more details.

Should I just reinstall the processors with your recommendations in mind?

Thank you.

Python 3.6 or higher will fix the last error. You will need to modify your PATH to point to the new python3.6+ in the ~/.bash_login or ~/.bashrc

It is best to NOT run and SeaDAS commands as super user. No need to "sudo"

What OS and version is the host
What version of Ubuntu
What version of SeaDAS
Did you install the SeaDAS GUI on the Virtual Machine

Hello.

I'm using Ubuntu 16.04.7 with Oracle Virtual Box.
I installed SeaDAS version 8.0.0 GUI.

Installing python 3.6+ made the installer in the SeaDAS GUI run now, however there is an error in the end:

Error: return = 1 : trying to run command = /home/torres609/SeaDAS/ocssw/bin/ocssw_runner --ocsswroot /home/torres609/SeaDAS/ocssw update_luts modisa
This is the last step in the installation, so you can complete the installation by running "update_luts modisa" in a terminal, or, for more details if an error occurs: "update_luts -v modisa".
** Files utcpole.dat/leapsec.dat are not present on hard disk.
** Running update_luts.py to download the missing files...
is because you have not yet successfully run "update_luts modisa" using your user privileges (note that the error messages are not completely accurate -- many of use no longer use hard disks, and the missing files may be present in your _filesystem_, just not where the script "expects" them to be. The second message needs updating from the SeaDAS 7 OCSSW software which used the ".py" extension for Python scripts:

Code: Select all

% grep update_luts $OCSSWROOT/bin/modis/*.py
/home/gwhite/ocssw/bin/modis/modis_GEO_utils.py:                print("** Running update_luts.py to download the missing files...")
/home/gwhite/ocssw/bin/modis/modis_GEO_utils.py:                print("** Running update_luts.py to update files...")
As previously mentioned, but worth repeating: do not use "sudo" to install or run SeaDAS 8. You may encounter some lingering problems with file ownership or locations (it is possible that utcpole.dat/leapsec.dat _are_ present, but were downloaded to a location in "root's" directory). These are generally easily repaired if you are comfortable with the linux permission system, but a mistake can result in irreparable damage.

Thank you for your reply, however I encountered an error when using update_luts.py.

Hello.

It seems that exporting OCSSWROOT path did not work. I also tried adding OCSSWROOT="/home/torres609/SeaDAS/ocssw" to the /etc/environment and /etc/profile, but it didn't also help with the error.

Similar error encountered:

Is there additional things I can check or do in order to address this error?
