Does anyone know what these errors indicate? My gpf node is apparently being run, but it isn't doing what I expect it to do. Both pconvert and gpt commands both generate a huge number of errors when I try to export geoTIFF or normal TIFF files from an L2 netCDF generated from L1 Landsat 8-9 Data even when the formatting of my commands matches what can be found in SNAP's documentation. Any insight into what is happening, or how I can figure out what is causing these warnings would be appreciated.

These commands were downloaded as part of SeaDAS's application, which is what I am using, through wget. I have never tried downloading SNAP on its own. I am also running this on an M1 MacBook Pro 14. I most recently got this error on 09/29/2024, but it was also happening since 06/2024.

Which version of SeaDAS are you using?

Hi, I'm getting the same issue with Seadas 9.1.0 how do you managed to solve it?

This warning stood out -
WARNING: org.esa.snap.core.util.ServiceLoader: org.esa.snap.core.gpf.OperatorSpi: Provider eu.esa.snap.snappy.gpf.PyOperatorSpi could not be instantiated
java.lang.NoClassDefFoundError: org/openide/util/Lookup

It will be great if you could do "SeaDAS-Toolbox -> Software & System Info" and post the result here. Also, if you could provide your gpt command and the sample file, it'll help us replicate the error

Thank you for the replies. I was able to solve this issue.

I believe the tools for gpt and pconvert were never ported to SeaDAS 9.0, so you can't use them in this version yet. I solved the issue by using them in SeaDAS version 7.5.3. Once I did this they worked normally.
