NullPointerException when I calibrate a GeoTIFF+XML subset of a Sentinel-1 product

snap
#1

Hi,

On Ubuntu:

I’ve generated, using snap/bin/gpt tool, a subset of a Sentinel-1 zipped product and saved the resulting subset in GeoTIFF+XML format (to be able to radiometrically calibrate it later).

After that, on the Snap GUI, if I take the resulting subset of the product and apply a radiometric calibration (or speckle filtering…), the operation seems to succeed but I always get the following java.lang.NullPointerException:

Does it affect the proper functioning of the operation?
Thanks.

I’ll take a look. Generally you should save to dimap if you want to continue to process and then finally export to some other format.
