Indeed @ABraun you are right.
I am afraid the study area is too large. Could you please say how many burst and subswaths are contained in your AOI and which is the RAM of your computer?
After installing successfully all the necessary software packages, StaMPS should work smoothly (except for Step 2 where you have to update your ps_load_initial_gamma.m in the matlab folder under StaMPS-4.1-beta).
Let me share to you my StaMPS_CONFIG.bash and StaMPS_CONFIG.tcsh files as shown below. Just change the username (i.e. ryeramirez in this case) to an appropriate one. Please note that I am using snap2stamps for the pre-processing part.
Below is the screenshot for sourcing StaMPS (and TRAIN).
Again, this should work smoothly if you have the correct directory paths.
I hope this helps.
Thanks also to @ABraun and @mdelgado because I came up with my own documentation about downloading, installing, and running the many software packages for PSI analysis using StaMPS.

What about the HW resources?
@mdelgado @ABraun @thho @CFEgildan71
I have re installed os again and run the stamp and still am unable to get the result
As it remained unanswered so far: Do the folders you have exported from SNAP look alright?
- geo
- rslc
- diff0
- dem
Their content should look similar as here: Workflow between SNAP and StaMPS
thank you for reporting.
Well…
could it be related to the gcc version employed?
Which one you used to compile the code in the stamps/src folder?
@Am not quite sure whether it is related or not…
I found it on CentOS … so this is why I am asking.
@now am simply runing default stamp(1,1) without any command
in which step i should have to insert?
setparm(‘insar_processor’,‘gamma’)
and
setparm(‘scla_deramp’, ‘y’)
you can set the parameters in the beginning and they apply whenever the corresponding step uses them
Please have a look at this great documentation of all parameters: https://gitlab.com/Rexthor/gis-blog/-/blob/master/StaMPS/2-4_StaMPS-steps.md
Setting the processor to “gamma” does not make sense to me when you prepared the data in SNAP.
@ABraun I have already processsed up to step2 is it needed to go back or inserting the parameter at step 3?
whenever you change a parameter, you have to reprocess all steps which included it.
You can check in the source code where each parameter is used: https://github.com/dbekaert/StaMPS/blob/master/matlab/stamps.m
as you see in line 121, insar_processor is used in step 1, so if you want to go sure that changes will correctly be applied, you have to run again from step 1.
test_result!
very good, congratulations on getting through the technical part!
Thanks alot @ABraun… this is the area with out subseting the study area…is there anyway to subset the map in matlab or other mapping softwares?..and i need the result to be in mm/year rather than rad/year what i have to do?
