Workflow between SNAP and StaMPS

I’m using the 3.3b1 version, by the way

I have sent you already a private message. Please check


how to solve the “already contains…”?


do you have both VV and VH in your stack?

hi Abraun

Yes, I have HH and VH in my stack.


Try to reduce your data to HH only at the beginning. This saves a lot of time (and disk space) and you need only one polarization anyway. I cannot promise that this caused your error but chances are good that there is no confusion between the bands any longer.

Thanks! I try to it!

I am a freshman at SNAP&StaMPS. I have learned a lot from here, thank you all.
I successfully ran mt_prep_snap by cygwin64 (using a modified version provided by someone else on the web). But after running mt_prep_snap, the matlab automatically jumped out, said ""Warning: Name is nonexistent or not a directory: \StaMPS-4.1-beta\matlab:

After that, I opened the matlab from the terminal and show as the second picture.

I don’t know what to do. I hope that someone can help me,please . Thank you very much.
ps. my matlab is windows R2016a.

I want to know how to configure matlab under cygwin64,i need your help

Your screenshots are too small to be readable I’m afraid.

I found a solution of this problem.!topic/mainsar/MDMV9yXDl1g
But it’s too simple, I can’t understand how to execute. I have done creat a startup.m and addpath, but I don’t know how to correct “the call of matlab scrip”
Thank you very much

when i run mt_prep_gamma in cygwin64 like this:
and the bash error occurs,how to deal with it

did you modify and source CONFIG.tcsh as described in the stamps manual?

see here: How to prepare Sentinel-1 images stack for PSI/SBAS in SNAP 5

no I have not done it ?my system is under cygwin64
i need your advice sinceresly!

does source like this?
and what to modify?

please read the manual. Chapter 2 - you need to tell StaMPS where the installed programs are.

Sorry, but I can’t give any more advise on cygwin - it didn’t work for me and causes new problems.

can you gudie me to pass the first step,mt_prep_gamma

all i have done is in the SNAP,so in the .bash file I dont know which to edit!

if you edit StaMPS_CONFIG.bash and execute it every time before you are going to use StaMPS, you don’t need to modify the system’s bash. You can do either the first OR the second option - both make the StaMPS scripts available to your shell.

another problem,the I download the,and do i need othe process to triangle(have unzipped)image
