recep, Kelly, et al: I see what's happening now. I provided auxiliary files in a folder, assuming that they would be put on your MATLAB path. You can either add those folders manually to the path, or drag the files out of the folders, or issue this (or equivalent) command:

addpath(genpath(fileparts(which('MorphTool.m'))))

Let me know if that addresses the issue, please.

Please try again; I believe that the current version includes all the files you need to run this. (Please let me know if there are any additional issues with MorphTool...).
Thanks, Bret

Great piece of work, thanks.

Very nice utility
