I have almost 600 dcm files saved into one large folder that I want to load into my MATLAB code to read the data files and print out a grayscale image. I am not sure how to call the 600 dcm files. I tried dicomread but it is not reading. Any help would be appreciated.

@Walter Roberson Do you know how to use VideoWriter and writeVideo to save my movie player video to my computer folder?

Yes, just like the VideoWriter documentation shows for those functions. Just make sure that when you pass the file name to VideoWriter() that you pass the complete path, such as
filename = fullfile(output_directory, 'XY_view.avi');
obj = VideoWriter(filename);

@ssmith, please see a variety of demos attached where I deal with videos.
You should be able to adapt one of them to make your video. For example to create a zoomed video, extract the portion of the image you want to zoom into, then resize it, then write it to the output video.

data = folder('scans');
scans = data;
I think I need to use VideoWriter but I am not sure how to do that

"folder()" is not a function. In my ExtractMovieFrames.m file, I show you how to create a movie from a bunch of individual still images. Use that.
