How to prepare Sentinel-1 images stack for PSI/SBAS in SNAP

Let me ask you a question,

What is the reason of applying stamps(1,1)? And how it works, or what is behind this script?

These questions for you to think about the scripts goal, not to answer me.

The other issue, I’m not sure about the validity of running StaMPS scripts , under cygwin, because many of other colleagues faced up this problem before , you could find their complainants using StaMPS under cygwin.
