Oh, I didn’t know that, sorry. In this case, it seems fine!
Thank you very much for the info, your fix worked for me.
Hi everyone, I’m running Stamp s and at step 1 it gives me an error message ps_load_initial_gamma. I checked the snap export and everything is ok.
The error is on line 70. I share the screenshot.
I am not a matlab expert I ask for your help, thanks to anyone who can help me.
Please try below one.

thanks suribabu but it didn’t help, i decided to modify line 69 by removing the +1.
I would like to ask you two questions.
- is it correct what I did?
i don’t understand how it works, but it seems to work.
i share the screenshoot and the modified file.ps_load_initial_gamma.m (7.3 KB)
I hope I didn’t make an irreparable mistake.
2)I would like to understand why it doesn’t work, does anyone have any ideas?
Thanks for the support
Instead of changing code. Please reprocess the mt_prep_snap step once again. I feel changing code is not a good idea because it’s working for most of the users.
ok thanks suribabu for the advice I am re-running mt_prep_snap with these parameters 0.40 4 26 70 200 because the export contains two complete iw’s (IW2 and IW3). In this way the patches contain about 5 million pixels, is this correct approach?
SNAP providing only for one swath right (IW1 or IW2 or IW2).
How to do IW1 and IW2 combinedly at a time in SNAP?
I followed the method here on the forum on the Workflow between SNAP and StaMPS tread.
it is very useful

How many images are you using for Stamps export?
I performed a test with 6 interferograms. The final project will use 137. I decided to make 6 product stacks. What do you think? Could the test be too few interfergrams?
Minimum 20 interferograns required for StaMPS(mentioned in this forum only). Better go for python wrappers.
Thanks suribabu for the help, I am exporting 16 more images. I hope this solves the problem. I have tried mt_prep_snap again, it does not give any error, no empty interferograms.
One more solution for this without unintalling the Matlab, insar_processor Changes Doris to snap.
like below.
setparm(‘insar_processor’, ‘snap’)
hi @suribabu , I imported all 131 images, I used mt_prep_snap with the following setting 0.4 26 4 70 200, I restored the ps_load_intial gama script but now it gives me an error when it gets to PATCH_3 I add a screenshot:
I read on the forum to double check all the interfergrams and @ABraun says to execute everything on a single PATCH (Workflow between SNAP and StaMPS - #503 by Gijs), how can I solve it according to you?
what did you mean by “Better go for python wrappers”?
One last thing to ask @suribabu, the last post you wrote was about my problem "One more solution for this without unintalling the Matlab, insar_processor Changes Doris to snap.
like below. "?
thank you all for the help. I am learning a lot.
this is only an option when your area is small and the error is related to the merging of the patches. Can’t say what’s the reason in your case, sorry.
dear @ABraun , i checked pscands.1.ij files in all 131 patches and there are many empty files. But I checked the files in rslc and diff0 there are no empty files. i checked the ifg there are no wrong files. Maybe there is something wrong with mt_prep_snap, I’m trying with less patch, is that wrong?
The result of the check follows:

Thanks for support
based on the error message you have 100 patches which would be way too much.
Please delete your working folder and run mt_prep_snap again with only 4 patches (command ending with 2 2)

May I know, from where you downloaded the StaMPS program (source).

Dear @ABraun and @suribabu , apologies for the delay in replying but I am currently very busy. However, I wanted to thank you again for your time.
Replying to @suribabu I followed as a guide this Using StaMPS/MTI for PSI Analysis – Part 1: Installation and Setup | GIS-Blog.com and the links for the software. In particular for the stamps source is taken from here Release StaMPS 4.1-beta_20180814 · dbekaert/StaMPS · GitHub .The guide I followed is by user @m477h145.
Back to @ABraun I am running mt_prep_snap as you recommended, I will keep you updated.
Again, thank you all for your support and your time spent to my troubles.
