Function

   Displays a non-overlapping 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
   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.

   dotpath is very similar to the program dottup which 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.

   Using a longer word size thus displays less random noise, runs
   extremely quickly, but is less sensitive.

   dotpath finds all matches of size -wordsize or greater between two
   sequences. It then reduces the matches found to the minimal set of
   long matches that do not overlap. This is a way of finding the
   (nearly) optimal path aligning two sequences. It is not the true
   optimal path as produced by the algorithms used in water or needle,
   but for very closely related sequences it will produce the same result
   and will work well with very long sequences.

   If you wish to compare the path found by dotpath to the set of all
   matches found then the qualifier -overlaps will show all matches in
   red except for the matches in the minimal path which are shown in
   black, as normal.

Output file format

   In normal operation, a dotplot image is displayed.

   With the -data qualifier a file of the positions of the matches in the
   minimal non-overlapping set of matches is output.

  Output files for usage example

  Graphics File: dotpath.ps

Warnings

   If you give a small word size with a very large sequence you will run
   out of memory. If this happens, try again with a larger word size.

Diagnostic Error Messages

   None

Exit status

   It always exits with status 0.

   Program name                       Description
   dotmatcher   Displays a thresholded dotplot of two sequences
   dottup       Displays a wordmatch dotplot of two sequences
   polydot      Displays all-against-all dotplots of a set of sequences

   This program is closely based on dottup with the addition of by
   default displaying only the minimal set of non-overlapping matches.

   This program uses the same algorithm as diffseq for finding a minimal
   set of very good matches between two sequences. diffseq may be more
   convenient if you are looking at the differences between two nearly
   identical sequences.
