I have created a Stack (Backgeocoding) of 12 SLC Images and then created a subset fro my study area. After that when I am applying Debrust for the Subset then I have this error. It is indeed very important to create Stack >> Subset >> Debrust to work with a lot of images. I really need a solution.
It is to inform that my study area is in a single IW but the sub-swath size is different for all images (look at the picture).
