Dotty Plotter
for Apple Macintosh computers
version 1.0

Dotty Plotter is a tool for drawing dot matrix comparisons of sequences in 
molecular biology.  

Dot plots are used to view all areas of homology between two nucleic acid or 
protein sequences.  Dot plots are useful for determining if there are one or 
more segments of similarity between sequences.

This first release of Dotty Plot contains a minimum of features. I hope to 
improve Dotty Plotter's sequence size and memory limits, and add features. 

Speed of Dotty Plotter.
Times for 2000 x 2000 sequence comparison (Blue.Seq x BlueKsm.seq) with a 
15:25 stringency:window, results in 2407 dots plotted.

This program may be obtained from the net.bio.net archives by anonymous
ftp.  It is currently in the /receive directory as "dottyplot.hqx".  You
will need BinHex 4.0 software to convert the .hqx to the self-extracting
archive. Alternately, you may ask me for a bitnet/internet mailing of 
dottyplot.hqx (180 kbytes), or snail-mail me a formatted 3.5" disk.
