Findind NANs in unformatted image data [message #83641]

Hi, I'm trying to open unformatted floating point images, add them together, and save the sum as a unformatted floating point image (see below). I can open the images, display with TVscl and print out a bit of image info (including the correct pixel values). I get an error 'Program caused arithmetic error: Floating illegal operand'. I understand this may have something to do with NANs in the images but I can't find any. I've also tried opening just one of the images and saving it using writeu. The result is an image with a few really low values and nothing resembling what I expect. ANY suggestions are very much appreciated!
