How do I define an input folder to execute and build a standalone application in MATLAB?

I have defined a folder to read my input images from in my matlab code. How do I change this if I am to build my program into a standalone application? Because, now when I run the .exe file my program doesn't run as expected, which I'm guessing is due to this. Can someone help?

% Define path to folder with images to processs
  Dir = 'C:\Users\username\Documents\MATLAB\FolderwithImages';
  % % Read images from Images folder
  Images = dir(fullfile(Dir, '*.tif'));
  for r=1:length(Images)
  <<algorithm>>
  end

Please explain, why you guess, that the shown code contains the problem. At least I cannot reconsider this.

The shown code does not contain a problem. Perhaps you forgot to include the path when opening the image files.

Dir = 'C:\Users\username\Documents\MATLAB\FolderwithImages';
Images = dir(fullfile(Dir, '*.tif'));
for r=1:length(Images)
  ImageFile = fullfile(Dir, Images(r).name);
  <<algorithm>>
end

It might be smarter to get the fiolder using uigetfolder and perhaps store the last used folder as preferences for the next run.
