No ifgs folder creation after running "sarvey_plot"

[svenborgstrom]

Good morning Andreas,
I processed a stack of S1 data over my AOI and I got regularly the miaplpy folder with both slcStack.h5 and geometry Radar.h5 files. They both look fine so I moved on after setting up the config.json file and run the first step (sarvey -f config.json 0 0). I got the 3 files in the pic folder, besides the background_map.h5... etc... The problem arises with the sarvey_plot script (sarvey_plot ifg_stack.h5 -i) as I'm not able to get the ifgs folder, with an error message "WARNING - Cannot plot ifgs from /path/to/miaplpy/outputs/ifg_stack.h5. I gave permission on all files in the folder (chmod +x *).
I tried many times but I get always the same result.
The full path in the config.json file is correct for both inputs and outputs folders.
I hope I was clear enough otherwise please ask me if you need more info.
Best,
Sven.

Dear Sven,
Thank you for sharing your experience.
In version v1.2.0 of SARvey, the function sarvey_plot with the argument -i requires the path to the slcStack.h5 file instead of the ifg_stack.h5, i.e.

sarvey_plot -i inputs/slcStack.h5

You can use this functionality to view the interferograms and amplitude images even before starting the SARvey processing, as the interferograms are computed on-the-fly for the visualization only. More details can be found here.

Please let me know if this solved the issue.
Best, Andreas

Hi Andreas,
the command you suggested works fine for amplitude and phase visualization but I don't get the "ifgs" folder inside "outputs/pic".
The command "sarvey_plot outputs/ifg_stack.h5 -i", suggested in the detailed guide of the demo dataset, unfortunately still give me the same error outlined above.
I have version 1.2.0.
Best,
Sven.

Dear Sven,
thanks for your feedback. There has indeed been a change from v1.1.0 to v1.2.0 in the definition of the command "sarvey_plot -i". Previously, it was creating the interferograms and storing it to the pic/ifgs directory, but now it only shows the GUI with amplitude and interferogram images. I am sorry for the confusion.
We will discuss how to handle this and change either the code or documentation accordingly.
I hope the rest of the processing is working fine for your study area. Let me know if you have any further questions, comments or suggestions.
Best, Andreas
