           residues in the sequences. \
           If you are reporting a word size of 1 (single bases or residues)
           then there is no point in using this option because the calculated
           expected frequency will be equal to the observed frequency. \
           Calculating the expected frequencies like this will give an
           approximation of the expected frequencies that you might get by
           using an input file of frequencies produced by a previous run of
           this program. If an input file of expected word frequencies has
           been specified then the values from that file will be used instead
           of this calculation of expected frequency from the sequence, even
