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=) ]
