Hello, We have a hyperspectral imager that cover the region between 670 nm and 780 nm. Thus we don't have a water retrieval band. I used FLAASH to perform some atm correction and I selected NO water retrieval. However, I still got the error that says ""No water absorption channels selected". Is there a way to bypass the water retrieval?

Can you post your template that is written to the output directory specified in FLAASH? Also, can you turn on water retrieval, set to 820nm (if not already set) and then turn it back off again? Does this change the error?
