Description

Hi,

I'm looking for a way to replace NULL values in ISIS with a set number (such as 0 or -1). I know how to do the reverse (replace numbers with NULL values) using "specpix". Is there a function in ISIS that does this?

Thanks, Catherine

I think the program stretch might do what you need. I can't recall having used it this way, but according to the documentation you set special pixel values to a different special pixel value or a double value.

Yes! That worked. Thank you.
