First scale your image array, a, to be in the range 0-255 normalized_a = uint8(255 * (a-minValue) / (maxValue - minValue)); Then save it with imwrite imwrite(normalized_a, fullFileName);

I'll send you email with the .mat file. thanks, diane ImageAnalyst <imageanalyst(a)mailinator.com> wrote in message <e7203442-8907-421f-973e-80d5561ea48d(a)e23g2000yqd.googlegroups.com>... > That's because you're saving the figure not the image so you're saving > a screenshot of the figure window.
