Dear all,  
I am working on SDR model (Version 3.7) for a larger river basin has an area of about 312,812 km². I am facing some issues such as, appearance of No data pixels in the stream tif., usle tif. and rkls tif. further it’s not generating any outputs other than this. I am attaching the log file and map of no data pixel, here…

Thank you all.
