I installed the SeaDAS toolbox beta with SNAP 7.0, but get the following error trying to execute a gpt graph that reprojects a L2 file. Things work fine from the GUI and using SNAP v6 without SeaDAS toolbox.

I'm running on RHEL 7. The input is a L2 generated by l2gen.

gpt -c 7G repro_graph.xml -t aqua.2019227.GL1.dim -f BEAM-DIMAP -Pfile=A2019227190500.GL1.L2

Hi Andrew,

Thank you for reporting this problem. We've replicated the problem and have an idea about its cause. Please uninstall SeaDAS toolbox when using gpt for now. We will resolve this issue with the next SeaDAS Toolbox release.

Thanks,

Aynur
