e numbers 0-9 and finally by 
        the symbols '*', '-' and '.' in that order.  
        (Note that '?' is not included in this list because it is never
        allowed to be a core symbol.)
        This ordering is used to determine the order of the columns in 
        motifs output by MEME Suite motif discovery programs.
        Note: The order in which you specify symbols within the
        core symbol section of your alphabet file does not matter.</p>
