Snap2stamps error

Hi,
I am getting the following error in my 5 images, what should I do?

I think the processing went well. There is no error

I have a question if you wouldn’t mind.
As you can see here, in line number 69, the topographic phase removal option is disabled,

I have used this graph file during the automated processing step “Master-slave coregistration and interferogram generation” and yet topographic phase bands were created. How is that possible ?
and the tutorial never mentioned editing this line during for the pre-Stamps-processing chain.

mdelgado · January 30, 2023, 2:02pm

Just scroll down and you will find the operator TopoPhase Removal (line 106)

You have just needed to go a bit down to get it clear.
Obviously, no need to rise an unexisting alarm to everybody.

Best,

Shadi1 · January 30, 2023, 2:22pm

This is embarrassing, I thought it was the reason why all the interferograms and velocity maps of my study area still contain persistent topographic pattern even after StaMPS processing. I apologize for such disturbance I have caused

mdelgado · January 30, 2023, 3:43pm

No problem!
It can happen to everybody.

The main reasons for topography alike signal could be: 1) not too accurate DEM, 2) atmospheric signal link to the topography

Enjoy the processing

Hi dear @mdelgado sorry to ask but I am trying to use the PSI method and I got this error:
python2.7 slaves_prep.py project.conf
Traceback (most recent call last):
File “slaves_prep.py”, line 16, in
from pathlib import Path
ImportError: No module named pathlib
I have used this before but it is not working now any suggestion?

mdelgado · March 28, 2024, 12:22pm

That was specified on the user manual for the version 1

masoodhp · April 3, 2024, 10:47am

I used that but for some reasons it is not working. I think the problem is with ubuntu 22. so i think i should downgrade it.

mdelgado · April 5, 2024, 8:48am

I invite you to see the version 2 then, which includes a yaml file with all the dependencies which you can directly use to create your conda environment with the python dependencies.
