I gave these processes to much time. The most important thing is patience, I guess. I followed @bayzidul steps for processing PSI in previous posts. After I exported PSI export from SNAP, then I applied mt_prep_gamma and stamps steps under Linux. I used mt_prep_gamma_changed and ps_initial_gamma_changed files provided by this forum. Also I used matlab folder provided by @bayzidul which BREAK lines deleted all in .m files. My initial results are following and I processed only 5 months data.
NOTE: I dont like the visualise of MATLAB so I remapped the results with another program. Also I processed to big area for PSI velocity determination. I obtain 12 billion data each results. I am going to focus smaller area for next my study.
