I have been trying to process some Sentinel-1 data for deriving the C2 matrix followed by terrain correction in SNAP and encountering the error “java.lang.NullPointerException”. I installed a fresh copy of SNAP with the latest available updates. I have encountered this error in GPF module. When I try to process the data with the usual steps, it works. However, when I save any of the processed data, SNAP is only writing the first component C11 of the C2 matrix and the rest of the elements have zero values. This is happening for any of the saved intermediate processed data for example after split and deburst etc.
Any solution to this problem?
