Hi Mehrdad,
your atmosphere is perfectly fine and no problematic at all. Values of the phase are close to ambiguity so you have a phase jump from -pi to pi but that is normal, the phase is wrapped. So, I strongly suggest you not to discard any images because you would just waste precious data. Generally speaking, unless you have huge problems (in…[Read more]

Thanks. I’ve double-checked the graph and as per the image attached, is a full graph (with 11027 connections). The few interferograms I’ve plotted seems ok. Of course, I couldn’t manually plot over 11K interferograms but there are 11028 interferograms in the respective folder.

I’ve also tried to run it again using other filtering parameters for…[Read more]

1. you can neglect the “ding” message. it means the sound message could not be played. if you want to suppress it, uncheck “play sounds” in advanced parameters.
2. the coherence map generation was done in a few seconds. to me, it means no interferograms were included in the processing. since no messages are shown, it could be that your images…[Read more]

Just to complete this post with a good news:

On MacPro 2019 I ran

matlab -nodesktop -r “main(‘InputParFile.txt’);

and it worked while when running the -nodisplay option it gives me the error above.

so,
1. the script is not needed
2. the problem you get now is related to java. if you run the matlab gui and then from matlab you launch sarproz in command line mode, do you get the same problem? if not, then I guess we need to make a little modification, let me know.
3. regarding matlab 2021a and mac: since day 0, we suggest everybody to set up a…[Read more]

Hi Daniele,
Regarding Point 1 I tried to launch the Matlab with -nodisplay option.
We got the error below:

$ /Applications/MATLAB/MATLAB_R2021a.app/bin/matlab -nodisplay -r “main(‘/Users/Desktop/test_full_VV_Full_Graph/5_78/20180810_VV_1/InputParFile.txt’); quit”…

1.I do not understand why the script is useless. The way we work on the cluster entails that all the commands should be included in a script which then goes into a pipeline for processing.

you can e.g. run:
matlab -nodisplay -r “main(‘inptuparfile’); quit”
or you can use the compiled version

2.Yes when we run fig=main(InputPar.txt) in the Matlab…[Read more]

Daniele,
1.I do not understand why the script is useless. The way we work on the cluster entails that all the commands should be included in a script which then goes into a pipeline for processing.

2.Yes when we run fig=main(InputPar.txt) in the Matlab graphic interface Sarproz runs. Instead when we launch the same command from a script it…[Read more]

1. the script is useless. you can run sarproz on a cluster without graphic interface without that script.
2. so, forget the script. if it freezes, the reason is somewhere else. did you try to run it without the script?
3. before doing that, please update sarproz to the last version. get it running and use the manage version module to download the…[Read more]

Thanks for your answer, here is the contents of the “log file” :

Welcome to SARPROZ

MATLAB 9.10 (R2021a) 14-Nov-2020

No errors are printed, just the SARPROZ…[Read more]

it would be good to see the log file
we tried it and it works (even if I do not really see the use to call the main from within a matlab script)
probably the reason is not in the script rather is some other factors preventing the process to execute properly…

Here, I attached the “test.m” file I run from p-codes directory.

Good Evening in Taiwan time, Alfredo,
Thank you so much for your answer.

I have different date for my asc and des images. but the difference is not to large. however if you had successfully selected the point manually. You must need a formula to know incident angle in each PS point right? whats way that you through to reach that incidenct…[Read more]

Good morning Yunus,
from my experience, at the moment I do the same, i.e. using the multi-sense module or external GIS-based tools to produce the maps of Vertical/EW motion with some spatial averaging.

About the time series, what I do is to apply use the same formula used to derive the maps applied to some specific points, manually.

The…[Read more]
