       dotter - Sequence dotplots with image enhancement tools


              Dotter - Sequence dotplots with image enhancement tools.

       Usage: dotter [options] <horizontal_sequence> <vertical_sequence>
              [X options]

              Where  <horizontal_sequence> and <vertical_sequence> are file names for FASTA files
              containing the two sequences.

       Allowed sequence types:
              Protein  -   Protein DNA      -   DNA DNA      -   Protein
