I see:

Error using imread>get_full_filename (line 569)

File "frame1.tif" does not exist.

Error in imread (line 371)

fullname = get_full_filename(filename);

Error in test8 (line 11)

fixed = imread('frame1.tif');

The problem is that you do not have frame1.tif as a file on disk in the current folder, or on the search path, thus imread() cannot find it.

So are you saying I could just use photoshift(:, :, 1) insteasd of imshow(frame1.tif)?

Yes, if the first image is your "fixed" image that all other images need to be aligned to. In fact it would be better because then your images are the actual images instead of a screen capture of an image on a figure.
