Hi I used Goldstein filter on my interferogram product I have and it takes so long from guides I read I understands that I don’t have to use Goldstein and chatgpt say it is better to do that and I am not sure about it maybe it is my ram it Is 8g and in a 30g ram it would takes to 6 hours to do 12 images stamps export and I really not sure how it’s done but I have only use 5 images and gonna try for a stamps-export that would do a good job for a test so I go big later I wanna go for a snap+stamps here I would appreciate guide and hellp to do this I am new and just learn about master slave
Sorry just for my curiosity, are you asking for help even before starting? Had you tried to read even the README file of snap2stamps v2? That file helps
Yeah of curse I try I try so many times I just failed in it and hopes to find why it doesn’t worked I always end up with bad number problem at end and can’t figure out why and this system take so much time to complete simple tasks
Could you please provide any further information on your processing? project file could help, master image, AOI, etc, so we can try to help you. Otherwise it is difficult to find and help you overcome your issue.

this is exactly what i get
and how i work is like this
split-orbit-back geo coding-deburst-interferogram formation-stampsexport
i try add goldstein filter but it did’t worked, do i have to do unwraping for this ? i ask chat gpt and says no
Ok… what you are showing here is not snap2stamps … but the next step, which absolutely depends on the StaMPS code, and how you compiled it.
Please search about this subject which has been subject addressed many times in the past.
You shall not run any goldstein filter for PSI analysis, and the unwrapping part is done within StaMPS itself. Please read StaMPS manual on its github : GitHub - dbekaert/StaMPS: Stanford Method for Persistent Scatterers
i use snap8 to do snaphu export becouse using snap12 to do it make it imposible to do unwraping but using snap 8 solve that. do you think that would solve this problem as well?
The issue of above is NOT related to snap2stamps, SNAP or to snaphu, only to the way you compiled the stamps source code used for the mt_prep_snap step.
Please search in the forum as there are threads solving it.
Best,
