ok. I have the solution to my problem. I work with grayscale images
and they have only 6 diferent pixel values. From 0 to 6. I can
visualize the image because I created a 6-level-colortable to
visualize, but when I save it, I cannot see the image because the
pixel values are very low.
To save it the way I can actually see the image I have to use the
command:

image = bytscl(image)

Now I'm confused. Why did that work?

Thank you!
