Hi Chaitanya, Thank you for your response. I tried inserting the --format option. It still gives me the same error. I would be glad if you can describe the --scale function. It asks for , [-scale [src_min src_max [dst_min dst_max]]] How do you put a formula here? like "raster/10"
Thanks a ton! I think you have given me a way to do it.
