  PREFIX should be the directory that contains the directory 'ts_exper1'. If it is not
  provided or is empty, the default is [userpath filesep 'Documents' filesep 'NDI'].

  If TESTING is 1, then PREFIX is taken to be [userpath filesep 'Documents' filesep' NDI filesep 'Test'], 
  and the files are copied to the temporary directory before proceeding so that the files 
  in the directory called PREFIX are not touched.
