Input files in graph xml file to run gpt command

[ZahraSad]

Hi,

I’d like to run an automated change detection processing using GPT. I prepared a graph using GraphBuilder using my input SAR images, then I tried to modify the .xml file to remove read and write nodes in the .xml file, to run gpt.

below shows my original .xml file to read the two images and then the next steps (just pasted the calibration after reading in below):

below shows my edited .xml file to remove reading the two images and then the next steps (just pasted the calibration after reading in below):

and then I run:

./gpt -e path_to_Graph.xml -t path_to_out put.dim path_to_firstS1image.SAFE path_to_secimage.SAFE

I received the below error:

Could you help to figure out how to edit the graph.xml file to run gpt command using this graph for every two SAR images as input?

Thanks

I solved the issue just by changing the original graph.xml file as bellow:

and then run:
gpt path_to_xmlfile -Pinput1=path_to_input1 -Pinput2=path_to_input2 -Poutput=path_to_output
