can you help me with this error?

Just install snaphu

can you please tell me, what is the results that need to b shown after finished processing the stamps?

hello sir, I want to ask something, I got the result for my deformation, but the PS POINT did not lies on the coordinate for my monitored stations using GNSS as validation, is there a possible chance for me to improve my processing inside stamps?

Have you solved it yet? I have the same problem and would like some help!
