Mt_prep_gamma and stamps(2,2) errors in StaMPS-4.1-beta after GAMMA preprocessing

Hello everyone, the data source preprocessing is processed with GAMMA, and the error of the first photo appears when using mt_prep_gamma of StaMPS-4.1-beta, and it runs normally after changing to mt_prep_gamma script of StaMPS_v3.3b1, but continue to use StaMPS-4.1-beta to run in the Second step of fast When estimating, the number of PS points selected becomes 0, as in the second error, please tell me how to solve it.
