I have removed the "urgent help --->". The term "urgent" does not encourage users to help you.

Have you seen the FAQ? http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

Beyond that, if your code doesn't work and the FAQ code doesn't work, you're going to have to post your exact code for us to figure out what is going wrong. Can you view a single one of your images with imread() and imshow() without doing it in a loop?

The code shown here does not define F.

You're right. I just glossed over that and assumed the imshow was showing the intermediate value X. Yep, that would cause the problem, and shows how things can be solved sooner if people would just post the actual error messages.
