Problems running MintPy with HyP3

[anaferreira97]

Hello everyone!

I'm trying to run Mintpy with HyP3 processor but I'm having problems generating temporal coherence mask. The log file is attached.
I don't know why I'm not having enough reliable pixels. All my clip files have at least 80MB. Do you have any idea why?

Three interferograms have been dropped from processing due to not having the correct size. First, fix this warning by means of cutGeotiffs.py, as explained here.

********************************************************************************
WARNING: NOT all input unwrapped interferograms have the same row/column number!
The most common size is: (5769, 4707)
------------------------------
The following dates have different size:
	201223-210104	(5607, 4707)
	201223-210116	(5607, 4707)
	210104-210116	(5769, 4705)
------------------------------
Skip loading the above interferograms (3).
Continue to load the rest interferograms (2).

To better diagnose, could you try:

1. update your mintpy to the latest development version, and re-run?
2. upload the pic folder for us to see the data quality?

The recordings from previous years' UNAVCO course (https://github.com/insarlab/mintpy-tutorial#1-small-baseline-time-series-analysis-with-smallbaselineapppy) can be helpful, if you are familiar with what each step is doing or checking.

Hi yunjunz! Thank you so much for your feedback.

I already re-run the process and the error still occurs. My pic folder only have the txt and the config file...

Hi. As you can see in the generated file named network.pdf, the interferogram network is very poor and not fully connected:

***WARNING: the network is NOT fully connected.
	Inversion result can be biased!
	Continue to use SVD to resolve the offset between different subsets.
-------------------------------------------------------------------------------
number of interferograms: 12
number of acquisitions  : 14

fix this warning too, and rerun the process.

I second @mosyhey comment above.

You could run smallbaselineApp.py --plot to populate the pic folder. I will turn ON this behavior by default in the next commit (update: this is now implemented in #825).

I encountered the same issue, but I was using ISCE + MintPy. Have you resolved this problem now?
