I had the same for matlab 2018, so it is not caused by version.
I later managed to overcome it by carefully checking if the output from SNAP was complete and then using the updated scripts provided by Katherine (see the overview post here: About the STaMPS category)
It is also a good advice to run StaMPS in matlab only step by step and check if all results were written correctly because otherwise they are missing in the subsequent steps without major warning.
Run single steps like this: stamps(1,1), check results, stamps(2,2), and so on.
Thank you very much.
i have followed all the steps in order to export data to StaMPS.
I have installaed StaMPS and I have the new 4 directories created after the export.
I have copied and replaced the two script that I have found in this forum respectively inside bin and matlab folder of StaMPS.
Now I have a big problem because I am not able to proceede.
I know that I have to run the script “mt_prep_gamma” but the terminal says–>command not found.
I have tried more times but I have not results.
So, I need someone that please tell me the steps that I have to follow:
where put the folder “stamps”
-where put the folder “stamps export”
from wich folder I have to run the script"
-the command that I have to type in order to run sthe script
I’m using cygwin on windows.
Please, I need these information.
Thanks.
Thanks,
I have added the PATH where there is my script and after navigate into the folder where there is the export but I had no results.
it says command not found:

Hi dear, can you pls explain to me step by step of ps analysis using 14sentinel images?
I read your steps above, but I cant understand if I should genrate coreg master-slave1 to master -slave2…so on…seperately first , and then I should creat 13 ifg seperetaly again??
after that I should creat stack of 13 coreg pairs, and then I must creat 13 ifgs coreg??? Am I wright??pls help me
Many thanks for sharing your experience. This forum was very useful to process 19 S-1 TOPS IW using SNAP 6.0 and in Linux, StaMPS 3.3 and Matlab2018.
But now I have some questions about my results :
The relative LOS displacement (see below) is higher than expected. According to GPS result in this area -5mm/year +5min/year is more realistic. Moreover the fringes seem to be correlated to the relief though I soustracted the topographic phase during SNAP process.
When I try to use ps_plot(‘v’,2) to plot shaded relief topo as background, StaMPS returned an error « Cannot find demparms.in in this directry, parent or grandparent ». I used SRTM1 DEM during SNAP process and I suppose StaMPS uses the same one. That is correct ?
If fringes in the interferograms are correlated with topography it seems likely that for some reason the topographic phase removal was not performed properly.
Hey everyone. The forum has been very helpful so far in the SNAP > StaMPS workflow.
I’m running SNAP in Windows and MatLab/StaMPS in linux (Ubuntu)
I’ve hit a problem in Step 6 and could use some advice on solving it.
PS_UNWRAP, after Resampling phase to grid gets the following error:
“Index in postion 1 is invalid. Array indices must be positive integers or logical values.” (Screenshot attached)
