Thanks for testing and great to hear that it works. I’d have some more questions:
- When do you get the
java.lang.NullPointerException? After updating the tile size setting in the SNAP UI? or after running the graph (from the UI) with the new settings? - If you write to disk after applying the
TOPSAR-Splitoperator (per input product). What are the resulting image dimensions of the master and slave? You can check this in the*.data/*.hdrfiles relative to the output product directory. Seesamplesandlines. I wonder if there’s a mismatch between master and slave dimensions and whether the images are smaller than the tile size.
