orbit file not getting downloaded using stackStentinel.py

[pritha19]

Hi, I am new to the isce2 software and linux. Everytime am trying to processes the data using stackSentinel.py I am getting the same Index error : list index out of range

20190413 orbit was not found in the /home/iirs/pritha/project/orbits downloading precise or restituted orbits ... fetchOrbit.py -i /home/iirs/pritha/project/data/slc/S1A_IW_SLC__1SDV_20190413T002849_20190413T002917_026764_0301A2_2FA8.zip -o /home/iirs/pritha/project/orbits/20190413 sh: 1: fetchOrbit.py: not found Traceback (most recent call last): File "/home/iirs/anaconda3/envs/new_env/share/isce2/topsStack/stackSentinel.py", line 787, in main(sys.argv[1:]) File "/home/iirs/anaconda3/envs/new_env/share/isce2/topsStack/stackSentinel.py", line 750, in main acquisitionDates, stackReferenceDate, secondaryDates, safe_dict, updateStack = checkCurrentStatus(inps) File "/home/iirs/anaconda3/envs/new_env/share/isce2/topsStack/stackSentinel.py", line 626, in checkCurrentStatus acquisitionDates, stackReferenceDate, secondaryDates, safe_dict = get_dates(inps) File "/home/iirs/anaconda3/envs/new_env/share/isce2/topsStack/stackSentinel.py", line 283, in get_dates safeObj.get_orbit(inps.orbit_dirname, inps.work_dir) File "/home/iirs/anaconda3/envs/new_env/share/isce2/topsStack/Stack.py", line 1048, in get_orbit self.orbit = orbitFile[0] IndexError: list index out of range

can you please tell how to resolve this.

It looks like it cannot find fetchOrbit.py and you probably need to add the topStack tools to your path like

export PATH=/home/iirs/anaconda3/envs/new_env/share/isce2/contrib/stack/topsStack:$PATH;

following advice at https://github.com/isce-framework/isce2/tree/main/contrib/stack

You could add that command to your ~/.bashrc file so it is remembered.

Good luck!

Thank you, I followed the steps as you suggested. It downloaded 5 files, but again the same error is showing.

@pritha19, I noticed on the error message that the ""(" unexpected". I think the filename is the one causing the error because it was named as S1A_IW_SLC__1SDV_20210108T002908_20210108T002936_036039_043921_5541(1).zip. Kindly remove the (1) on the filename and try processing it again.
