Error: run_01_unpack_SLC - too many indices

[chofst]

Hello,

I'm trying to generate interferograms with topsStack. I tried to download the orbits with stackSentinel.py and received the following error:

Traceback (most recent call last):
  File "/home/celeste/pkgs/isce2/contrib/stack/topsStack/stackSentinel.py", line 1023, in <module>

    self.orbit =  orbitFile[0]
                  ~~~~~~~~~^^^

I manually downloaded the orbits and was able to make the configs and run_files folders. However, I am now running into the following error while running step run_01_unpack_SLC:

Traceback (most recent call last):

                   ~~~~~^^^^^
IndexError: too many indices for array: array is 1-dimensional, but 2 were indexed

Would anyone have suggestions on how to fix this? Thank you for your help.

Best regards, Celeste

Hi I also encountered this same issue. I fixed it when I deleted all my orbit data and re-downloaded the orbit data again when running stackSentinel.py.

Hi Panji, great. That worked for me. Thank you!

Hi I am having the same issue. I tried downloading the orbit files using Sentinel EOF and I obtain this exact same error (it is downloading the files from ASF) and I tried using the dloadOrbits.py script bundled with ISCE2 and then I encounter a different issue fetching missing orbits as reported in https://github.com/isce-framework/isce2/issues/421.

Would you care to share how did you download your orbit files?

[chofst]

I am currently using Sentinel EOF (conda install conda-forge::sentineleof). I run the command while in my SLC dir, which reads the SLCs in the dir and saves the output to my orbit dir.

example: /data/track/SLC$ eof --save-dir /path/to/orbit/dir

(conda install conda-forge:: eofsentinel - version of Sentinel EOF did not work for me)

Hi thank you for your answer, I have downloaded the precise orbits using Sentinel EOF from Copernicus Data Space Ecosystem as follows:

eof --search-path ./SLC/ --save-dir ./Orbits/

However, I am still having the same error after I attempt running the run_01_unpack_topo_reference step:

Traceback (most recent call last):

IndexError: too many indices for array: array is 1-dimensional, but 2 were indexed

Running ISCE2 2.6.4 on Python 3.10 I generated the interferogram workflow using the following command:

stackSentinel.py --slc_directory ./SLC/ --orbit_directory ./Orbits/ --aux_directory ./AuxDir/ --dem ./DEM/demLat_N65_N68_Lon_W137_W130.dem.wgs84 --polarization VV --workflow interferogram --swath_num '1 2 3' --bbox '65.618996 67.686104 -136.927795 -130.405411' --coregistration geometry --reference_date 20200701 --num_connections 3 --azimuth_looks 5 --range_looks 15ts

I have also attempted to manually download the orbits from https://s1qc.asf.alaska.edu/aux_poeorb/ obtaining the same error. It seems to me there is a problem parsing orbits files after the endpoint for downloading the orbits was changed.
