%%% Cleans up the workspace - useful to run in case you have any leftovers

%%% Adds the paths
addpath(pathtodata);

%%% IMPORTANT: it will seem like nothing exciting has happened here. 
%%% But if in your workspace you now see the structures such as 'subjects' 
%%% and 'badchans', then this has worked.
