Hi everyone,
I’m trying to detect subsidence over a region in Iran and i’m using sentinel1 slc images. I used phase unwrapping with snaphu plugin.I want to import the unwrapped files and I use the output image of goldestein phase filtering for “read-phase” , then the UnPhase_ifg_VV_… .hdr for “read-Unwrapped-phase” but I’m getting these errors:
for the first one It says file "already contains a band with name phase_ifg_vv_date " and for the second one “file could not be read”. I don’t know what am I doing wrong 
Please have a look at this post, it explains in details the unwrapping step,
