Thank you very much Stanislav !
All the best

Hi @ABraun ,
I started using the workflow between SNAP and stamps and I am currently facing the same problem as you did last month, namely that " Error opening file pscands.1.ij" message in the end of the mt_prep_gamma step. Did you by chance solve this problem?
Cheers,
Maryse
unfortunately not. Do you work on windows or linux?
I work on a Linux machine.
I think, that maybe the problem is due to this spelling error:
file name for zero amplitude PS: pscands.1.ij0
instead of pscands.1.ij
I think that the problem lies within the selpsc_patch script. I will try to get more information in the mainsar forum.
Maryse
alright, at least it is not platform-related.
You could be right about the variable pscands.1.ij0
But strange that it only happened to us… Please let me know if you receive an answer in the mainsar forum.
@ABraun, the solution is quite simple. Try to run mt_prep_gamma inside your “export” folder, like this:
mt_prep_gamma 20150806 /data2/…/Export_to_stamps/ 0.4 2 2 50 200
where:
mt_prep_gamma [your master] [full path to your working directory] [Amplitude disp.] [Number of patches in range] [Number of patches in azimuth] [overlapping pixels between patches in range] [overlapping pixels between patches in azimuth]
It worked for me, at least I didn’t get the error message concerning opening the pscands.1.ij file.
Unfortunately, I now got the same issue as @katherine before, namely that the pscands.1.ij file is empty…
you are right, thanks for clarification. It works for me now, too.
At least the error about opening pscands.1.ij is gone. But I can’t tell if the output makes sense, yet.
After SNAP export to STAMP, STAMP protsessing are possible Windows matlab?
you first need to run mt_prep_gamma

Please see also here:
The rest can be done in matlab.
I agree with you but some of us aren’t used to the matlab syntax. It is then hard to search for errrors and debug the scripts.
Hello everyone
I meet a problem when i run snap v5.03. To 22 SLC about sentinel-1A,i apply orbit files 、 split and back-geocoding, but when debursting, it processes only about 20% with 27 hours. My computer is 16RAM, I7CORES… I want to know whether you meet the problem . how can it process fast ? tell me , i will appreciate you.
Hi, Light,
I separated the set of images into two stacks with the same master , processed them separately and combined the results after export to StaMPS.
Katherine
hi, katherine, thank you, but i don’t know the StaMPS well. Can you tell me the details how to combine the results after export to StaMPS? Whether can i separate images into more stacks with same master?
Hi Light,
I combined the results of processing of two stacks before launching StaMPS after the SNAP’s procedure "StaMPS export’. I have explained my processing chain in the post How to prepare Sentinel-1 images stack for PSI/SBAS in SNAP 5 .
Good luck,
Katherine
Thank you very much, katherine

Dear @ABraun
The link to the tutorial of Dr Mahdi Motagh seems to be broken, It will be so nice of you if you could please send me a copy of this tutorial Email waqas782[at]gmail.com
Many thanks

Dear all,
I have an error i can not run ps_plot, i have finished step stamps(5,5) and i run it in the INSAR_masterdate folder but it doesn’t work, any help please?
_Error: File: /usr/local/StaMPS_v3.3b1/matlab/parseplotprm.m Line: 98
A BREAK may only be used within a FOR or WHILE loop, and then only within the same file as its corresponding FOR or WHILE statement.
Error in ps_plot (line 128)
parseplotprm % check if ‘ts’, ‘a_m’, ‘a_l’, ‘a_p’, ‘ifg i^th’, 'ext PATH ’ is specified
Can you please upload the tutorial of ps processing by Dr. Mahdi Motagh, if you still have a copy
As these materials are not my personal property I would preferably refrain from doing so, sorry.
Hi waqas782
If you get a copy about “SAR-EDU_stamps_Motagh.pdf”, please send me one Email winyydgn@gmail.com
Thank you!
