You are blindly reading in everything in the directory, but your directory contains Thumbs.db as well as whatever content you are expecting. You should be making your dir() more specific.

Change
DTrain = dir(dirNameTrain); % check dir command, in matlab documentation
to
DTrain = dir(fullfile(dirNameTrain, '*.jpg')); % check dir command, in matlab documentation
