Dear users of PAUP* (with large datasets),

PAUPRat, a tool to implement Kevin Nixon's (1999) parsimony ratchet with
PAUP, is now available for download from:

http://www.eeb.uconn.edu/grads/sikes/paupratweb/pauprat.htm

or ( if the first site is too slow, or down):

http://viceroy.eeb.uconn.edu/paupratweb/pauprat.htm


There are 3 versions for different computer platforms and a pdf users
manual:

Macintosh, Linux (intel), and Windows (DOS-prompt)

The program is as-is, without plans for improvements (but it did find the
shortest tree length for the rbcl  500 taxon dataset in only 20 minutes!
Your results may vary)

----------------------------------------------------------------------------

[for the Mac version: upon launching the program, click the button labeled
'OK' and then use command-Q to quit the program.

PAUPRat will have created a setup file that you will edit.

The minimum that needs editing in the setup file is the specification of the
number of characters in your dataset (nchar=) ]
