I only have five images to experiment - I want to get past the Segmentation Fault problem.
As you suggested, I have now checked REL_ORBIT, slice_num and PASS, and they are equal for all my data.
To answer your questions, I use snap2stamps python scripts before mt_prep-snap:
- Sort the slave images in separated folders corresponding to their acquisition time.
- Slave splitting (and slice assembling if needed) and annotated orbits replacement with Precise/Restituted Orbits.
- Coregistration and interferogram generation done per slave and subswath. Both amplitude coregistered master-slave stack and interferogram with elevation and orthorectified latitude and longitude coordinates are saved as output.
- StaMPS export is done providing for each pair coregistered stack and interferogram generated StaMPS compatible products.
snap2stamps python scripts:
slaves_prep.py – script for sorting slaves into the expected folder structure
splitting_slaves_logging.py – script for slave splitting (and assembling if needed) and orbit correction
coreg_ifg_topsar.py – script for master-slave coregistration and interferometric generation
stamps_export.py – script for ouput data generation in StaMPS compatible format for PSI processing

Thank you again for you assistance!
