Error in stackSentinel

[riyasmjgeo]

Hello All,

Greetings!
I got an error while running 'run_07_pairs_misreg' in the stackSentinel process-chain.
Type: <class 'isceobj.Sensor.TOPS.TOPSSwathSLCProduct.TOPSSwathSLCProduct'> <isceobj.Sensor.TOPS.TOPSSwathSLCProduct.TOPSSwathSLCProduct object at 0x7ffb1ed9d0a0> Running: overlap_withDEM ['--interferogram', '/home/luis/ops/coarse_interferograms/20211212_20211218', '--reference_dir', '/home/luis/ops/coreg_secondarys/20211212', '--secondary_dir', '/home/luis/ops/coreg_secondarys/20211218', '--overlap_dir', '/home/luis/ops/ESD/20211212_20211218'] module overlap_withDEM not found Traceback (most recent call last): File "/home/luis/apps/miniconda3/envs/stack/share/isce2/topsStack/SentinelWrapper.py", line 251, in <module> main(args.start,args.end) File "/home/luis/apps/miniconda3/envs/stack/share/isce2/topsStack/SentinelWrapper.py", line 242, in main cfgParser.runCmd() File "/home/luis/apps/miniconda3/envs/stack/share/isce2/topsStack/SentinelWrapper.py", line 54, in runCmd func_modules.main(self.funcParams[section]) AttributeError: 'NoneType' object has no attribute 'main'

The configuration used for stackSentinel is
stackSentinel.py -s ../slc/ -o ../orbit/ -a ~/Work/Sentinel-1_aux/ -w ../ops/ -d ../dem/demLat_S76_S72_Lon_E062_E073.dem.wgs84 -c 3 -z 6 -r 30 -f 0.70 -p hh -b "-74.579018 -73.772415 65 71" -W offset

In my first try, I tried to get maximum coverage in the bounding box (covered in all the SLC), with parameter -W interferogram. Then I shrunk the AOI from all sides to check if it was because of any overlap issue. Then I tried to run the same with -W offset as well. I do get the same error in all the cases and the process doesn't go forward as I am getting another error while running 'run_08_timeseries_misreg' as below:

Traceback (most recent call last): File "/home/luis/apps/miniconda3/envs/stack/share/isce2/topsStack/invertMisreg.py", line 158, in <module> main() File "/home/luis/apps/miniconda3/envs/stack/share/isce2/topsStack/invertMisreg.py", line 114, in main tbase,dateList,dateDict = date_list(overlapPairs) File "/home/luis/apps/miniconda3/envs/stack/share/isce2/topsStack/invertMisreg.py", line 50, in date_list d1 = datetime.datetime(*time.strptime(dateList[0],"%Y%m%d")[0:5]) IndexError: list index out of range Traceback (most recent call last): File "/home/luis/apps/miniconda3/envs/stack/share/isce2/topsStack/invertMisreg.py", line 158, in <module> main() File "/home/luis/apps/miniconda3/envs/stack/share/isce2/topsStack/invertMisreg.py", line 114, in main tbase,dateList,dateDict = date_list(overlapPairs) File "/home/luis/apps/miniconda3/envs/stack/share/isce2/topsStack/invertMisreg.py", line 50, in date_list d1 = datetime.datetime(*time.strptime(dateList[0],"%Y%m%d")[0:5]) IndexError: list index out of range

I installed ISCE2 using conda and after setting up the PATH in the usual way, the stackSentinel.py application was not included in the path. I had to find the application (stackSentinel.py) path and had to assign that explicitly in the PATH. I am stating this only because I wonder if the error happened because the application was unable to find any *.py file?
A detailed error report is also attached for reference.
error.txt

I can see that the directories ...../misreg/azimuth/dates and ...../misreg/range/dates are empty, so I guess the error occurred in all the pairs.
Could you please suggest where to start my debugging?
ISCE VERSION = 2.5.3. I supplied a combination of S1A and S1B in this process.

Thank you

Hey, I'm just looking over your question and it looks like maybe the bounding box argument is out of order in your stackSentinel.py script? You currently list it as
-b "West East South North"
The lat/lon should be listed as follows:
-b "South North West East"

Therefore the boundary box is currently not properly lined up with your frame. Maybe see if that works?

I am looking at a location in Antarctica and for that, the bbox coordinates are in correct order. Before creating the run files in stackSentinel.py, it checks for the overlap between the bbox and SAR data. In that check also, all the datasets were shown. So, I strongly believe it is not an issue with the bbox.

Another thing I have noticed is that I don't have any ***/reference/overlap/IW*/range_bot_**_**.off files present in my directory. Can that be the root cause?

No range offsets provided
rdict:  {'rangeOff1': '/home/***/ops/reference/overlap/IW1/range_bot_01_02.off', 'rangeOff2': '/home/**/ops/coreg_secondarys/20200121/overlap/IW1/range_bot_01_02.off', 'azimuthOff': '/home/*******/ops/coreg_secondarys/20200121/overlap/IW1/azimuth_bot_01_02.off'}

Hey riyasmjgeo, I met the same problem module overlap_withDEM not found while running 'run_07_pairs_misreg' and I just fixed it.

• First, I found the PATH '/isce2/contrib/stack/topsStack/overlap_withDEM.py'. Then I made it executable according to chmod +x overlap_withDEM.py, and tried to run it overlap_withDEM.py -h. It returned an ERROR just like <home path>/anaconda3/envs/isce2_env/lib/libstdc++.so.6: version GLIBCXX_3.4.30' not found]...`.
• Then I checked the dynamic library using strings <home path>/anaconda3/envs/isce2_env/lib/libstdc++.so.6 | grep GLIBC. Clearly, the results displayed info from GLIBCXX_3.4.1 to GLIBCXX_3.4.29 except GLIBCXX_3.4.30 due to there was only 'libstdc++.so.6.0.29' existing in the 'anaconda/lib' path.
• Finally, running conda install -c conda-forge libstdcxx-ng to update it and 'libstdc++.so.6.0.30' is available. Rerunning 'run_07_pairs_misreg' with no problem.

This worked for me, hope it can help u!

You are a savior @464658329-cmd it worked perfectly. Thank you so much
