Hi Ahmed

First, which images are you using, because it looks like your image doesn't has good métadata

Particularly, your image needs to have gain and offset define for radiometric calibration to be able to run

Hello Cédric Aurelien Nguimdo Matsaguim , Thank you so much for your good opinion. I have already done radiometric calibration. My image has all information that you have mentioned. This error was occurred due to long path of output file. Thanks

Ok

My output returns empty after radiometric calibration

Thank you S M Shamim Ahmed Tuhin I just had a similar issue and your comment really helped.
