Thanks gnwiii for clarifying that point, I hadn't realised.
Thank you xuanyang02 also, you were both very helpful and very clear in your explanations.

In another post I will ask you about the l2mapgen.

Searching the net, I found a python library called Pyresample, which seems to do the same as l2mapgen.
Do you know this python library? do you know if there is any significant difference?

Thank you xuanyang02!!

Thanks a lot

I was indeed able to write netCDF-CF files, but I had another problem. When I tried to test the .xlm with gpt, I realised that there is...

More information about the problem. When I try to load the .xlm file in SeaDAS with the batch processing I get this error: java.lang.NullPointerException at org.esa.snap.graphbuilder.gpf.ui.ReprojectionUI.initParameters(ReprojectionUI.java:122) at org.esa.snap.graphbuilder.gpf.ui.ReprojectionUI.Crea...

Hi, I'm new to SeaDAS gpt mode, and I've been trying to do the "Hello World" example from "https://seadas.gsfc.nasa.gov/help-8.2.0/GptCookbook/gptCookbookWorkflowEx01.html". I currently have SeaDAS 8.2.0 installed, and I'm on Ubuntu 22.1. I've made the WorkflowEx01.xml and Workfl...
