Function

   Displays a wordmatch dotplot of two sequences

Description

   A dotplot is a graphical representation of the regions of similarity
   between two sequences.

   The two sequences are placed on the axes of a rectangular image and (in
   the simplest forms of dotplot) wherever there is a similarity between
   the sequences a dot is placed on the image.

   Where the two sequences have substantial regions of similarity, many
   dots align to form diagonal lines. It is therefore possible to see at a
   glance where there are local regions of similarity as these will have
   long diagonal lines. It is also easy to see other features such as
   repeats (which form parallel diagonal lines), and insertions or
   deletions (which form breaks or discontinuities in the diagonal lines).

   dottup looks for places where words (tuples) of a specified length have
   an exact match in both sequences and draws a diagonal line over the
   position of these words. This is a fast, but not especially sensitive
   way of creating dotplots. It is an acceptable method for displaying
   regions of substantial similarity between two sequences.

   Using a longer word (tuple) size displays less random noise, runs
   extremely quickly, but is less sensitive. Shorter word sizes are more
   sensitive to shorter or fragmentary regions of similarity, but also
   display more random points of similarity (noise) and runs slower.

                    polydot      Draw dotplots for all-against-all comparison of a sequence set

                    dotmatcher, by comparison, moves a window of specified length up each
                    diagonal and displays a line over the window if the sum of the
                    comparisons (using a substitution matrix) exceeds a threshold. It is
                    slower but much more sensitive.
