Re: Python3.6 installation error in Ubuntu for SeaDAS

There was a Python 3.6 package for Ubuntu 16.04 (at https://launchpad.net/~jonathonf ) but it is no longer available. You can still install Python 3.6 from source: https://www.rosehosting.com/blog/how-to-install-python-3-6-on-ubuntu-16-04/ . SeaDAS 8 was, however, also tested with Ubuntu 20.04 (LTS)...

Re: download with wget serie of files

Have you reviewed the current https://oceancolor.gsfc.nasa.gov/data/download_methods/ ? For me, wget is not reliable, but I have had better luck using the python script. One thing to try with wget is the option to use wget's "--adjust-extension" option to set the extension. If there is an ...

Re: L2gen fail with exit code 1

The OCSSW system has a separate installer called "install_ocssw". I don't think uninstalling the GUI will affect the existing OCSSW install. The installer is a python script that can be run from the command line. There are detailed instructions at https://seadas.gsfc.nasa.gov/downloads/ un...

Re: l2gen not using specific settings

I think V2022.0 uses the new https://oceancolor.gsfc.nasa.gov/docs/f ... onvention/, so is not a drop-in replacement for existing workflows.

Re: OCSSW Installation error

You appear to be using Python 3.5. https://seadas.gsfc.nasa.gov/requirements/ states that you need Python 3.6 or above. Note that you may also need to install a suitable python3-requests package. When asking for help it is good practice to mention your OS version because others using the same OS ver...

Question: How to convert zero value to NaN in SeaDAS

Re: How to convert zero value to NaN in SeaDAS

SeaDAS has built-in support for missing value handling (see the properties for your new band). NaN's are commonly used with floating point data, but if your generated band uses integer values, your only option is to set a missing value in the band properties. If you use NetCDF4-CF format, missing va...

Re: I have problem about extracting multiple NetCDF files with multiple stations of interest

I attempted to utilize seaDAS at first, but because of my laptop's window operating system, I was unable to use the extraction feature. Thanks for the additional detail. I think pixel extraction should work in the SeaDAS GUI, but a laptop may not have the capacity (mainly RAM) to process many files...
