Data load

[Frank]

Hi Yunjun and all,

I am using HYP3 as well, but I guess I encountered the issue of data load. Hope you can give me some hints to solve the issue. Appreciated!

The step of data load seemed to be good, and then I proceeded to invert the network with the following said:

Input data seems to be geocoded. Lookup file not needed. generate_mask.py /home/jovyan/143_new/MintPy/temporalCoherence.h5 -m 0.7 -o /home/jovyan/143_new/MintPy/maskTempCoh.h5 update mode: ON run or skip: run input temporalCoherence file: /home/jovyan/143_new/MintPy/temporalCoherence.h5 read /home/jovyan/143_new/MintPy/temporalCoherence.h5 create initial mask with the same size as the input file and all = 1 all pixels with nan value = 0 exclude pixels with value < 0.7 create HDF5 file: /home/jovyan/143_new/MintPy/maskTempCoh.h5 with w mode create dataset /mask of bool in size of (1324, 1527) with compression=None finished writing to /home/jovyan/143_new/MintPy/maskTempCoh.h5 time used: 00 mins 0.1 secs. number of reliable pixels: 1 Traceback (most recent call last): File "/home/jovyan/.local/envs/insar_analysis/bin/smallbaselineApp.py", line 8, in <module> sys.exit(main()) File "/home/jovyan/.local/envs/insar_analysis/lib/python3.8/site-packages/mintpy/smallbaselineApp.py", line 1270, in main app.run(steps=inps.runSteps) File "/home/jovyan/.local/envs/insar_analysis/lib/python3.8/site-packages/mintpy/smallbaselineApp.py", line 1050, in run self.run_network_inversion(sname) File "/home/jovyan/.local/envs/insar_analysis/lib/python3.8/site-packages/mintpy/smallbaselineApp.py", line 559, in run_network_inversion self.generate_temporal_coherence_mask() File "/home/jovyan/.local/envs/insar_analysis/lib/python3.8/site-packages/mintpy/smallbaselineApp.py", line 614, in generate_temporal_coherence_mask raise RuntimeError(msg) RuntimeError: Not enough reliable pixels (minimum of 100). Try the following: 1) Check the reference pixel and make sure it's not in areas with unwrapping errors 2) Check the network and make sure it's fully connected without subsets

I checked the tempoalCoh and found the temporal coherence is all zeros. 

I also checked the interferograms using "!info.py $inputs_path/ifgramStack.h5", and found there is only one band, which may be the reason of zero coherence. Also the correct ORBIT_DIRECTION should be in DESCENDING, but I got ASCEDING.

I just found the data is only 7Mb for each igram, which may be resulted from cropping. Thanks all!
