image10 = allImages( :, :, 10 );
images2_5 = double( allImages( :, : [2 5] ) );
image2_minusImage5 = diff( images2_5, [], 3 );

Off the top of my head, that should do what you are asking, where obviously 'allImages' is to be replaced by whatever you called your image array.

See my attached demo. The first half extracts frames from a movie and saves them to disk as individual images. The second half reconstructs the video by reading in those images and using VideoWriter it makes a video file. You can just do that, though you won't have to call imread() since your frames are already in memory.

You could read it into a vector and then reshape. E.g.,

image = fread(fid, 128*128*128, '*uint16');
image = reshape(image,128,128,128);
