Step 6 error "changing unwrap_gold_n_win does not work"

To make sure I’m not missing a key element or concept of the the solution by@reyhanrere that could cause problems later, I’m listing the steps I took that seemed to work below. If anyone sees anything that’s wrong let me know.

  1. Using Band Maths I created lat and lon bands in the stack_deb_subset product
  2. Using File>Export> I exported the product in Gamma format
  3. I now have lat.rslc and lon.rslc files (among other .rslc files for the other bands in the product)
  4. Renamed lat.rslc and lon.rslc files to .lat and .lon (ex 20170704.lat)
  5. Replaced the original 20170704.lat and 20170704.lon files in the geo folder with these new files.
  6. re-ran mt_prep_gamma (updated version)
  7. re-ran Stamps(6,6) (Didn’t think this would work but tried it anyway.)
    Got a ‘matrix dimensions must agree’ error.
  8. So I started from step one and ran Stamps(1,6) and the unwrapping completed successfully.

Thanks for looking it over.

By the way, any idea why the lat/lon files created with the SNAP6.0 ifg stage still need to be replaced in this manner?
