Hello I’m have the same issue, I’m using the Dinsar method. I’m performing terrain correction on a file that has been import snaphu and phase-displaced, and on the snaphu import file (without phase-displacement). I want to create a stack of both files and then perform band correction. However, the same error appears. I’m followed this tutorial on youtube “PENGOLAHAN CITRA SENTINEL 1 UNTUK ANALISIS DEFORMASI MENGGUNAKAN SOFTWARE SNAP” by nur muhammad ikram
