I have downloaded Docker and SEADAS according to the instructions for the the upcoming ARSET training: https://appliedsciences.nasa.gov/get-involved/training/english/arset-overview-seadas-841-processing-analysis-and-visualization as well as https://seadas.gsfc.nasa.gov/client_server/ .The instructions provided on each differ in the code for how Docker is started/which image is used and the instructions for the class do not discuss changing the SeaDas Properties file - I think because changing the processor ___location does this automatically.

No matter which instructions I follow, I get the below errors that differ depending on whether I set the SEADAS processor ___location to Docker (first) or VirtualMachine (second). What is also difficult is that I did, at one point, have SeaDas working and was able to download the processors and complete a mosaic. However, I could not run processors to geolocate a level 1 file and use l2gen to create a level 2 file. To be honest, I am not sure what I did differently between then and now, but I uninstalled/reinstalled thinking that would correct the initial problem with the processors and it seems to have created a whole new problem that doesn't even let me get to the same point. I appreciate any help.

Hi there,

Please follow the instruction at https://seadas.gsfc.nasa.gov/client_server/ because we update it after each release of SeaDAS.

You posted the message that was displayed when you ran "Software and System Info" in SeaDAS Toolbox. We will take care of the error message in it. However, it should not affect the execution of OCSSW programs. Have you tried to install SeaDAS processors?

Thanks,
Aynur

Hi Aynur,
I appreciate the response. I had figured the website was the most current, but started with what was provided for the class. Yes, I have tried to install the SeaDas Processors. I get an error for that too, which I thought was linked to the info I shared before. The error code is the same no matter if the processor ___location is set to Docker or VirtualMachine. It is not clear from instructions which it should be set to. I assume Docker (it does it automatically and the seadas property file change on the website seems to indicate that). Any help is greatly appreciated! Amy

Hello. I also am preparing for an upcoming workshop and having errors from SeaDAS 8.4.1 install on a PC (Windows 11). I tried to follow the video showing how to Install a SeaDAS processor. I get the following error:

ocssw installation script failed to download.
Please check network connection or 'seadas.ocssw.root' variable in the "seadas.config" file.
possible cause of error: PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Hi Amy,

Can you send me content of ${user.dir}\.seadas8\etc\seadas.properties file?

Thanks,
Aynur

Hi mwraenqual,

Can you check the version number of Java on your computer?

Thanks,
Aynur

Hi Aynur,

I'm running Java Version 8 Update 201 (build 1.8.0_201-b09)

Can you also send me content of ${user.dir}\.seadas8\etc\seadas.properties file?

Thanks,

Sure can! Here's what I found:

Aynur,
The seadas.properties file content changes when I change the SeaDas Processor ___location (see below). I have also tried changing it to read exactly what it says on the Client-Server website. None of these seem to matter with operation. I've tried a number of combinations of things to troubleshoot.
