You are making a directory '/Users/mananmehta/Documents/MATLAB/dataset/stereo-pairs/cones' but then changing directory to '/Users/mananmehta/Documents/MATLAB/dataset/'.
Should you be changing directory to '/Users/mananmehta/Documents/MATLAB/dataset/stereo-pairs/cones'
If this is the case, I'd suggest putting the directory name in a variable and then using the variable in both places to avoid this kind of error.
