Announcing the first full public release of

     CPC - Common Principal Component Analysis software
	 
Available at <http://wbar.uta.edu/software/cpc.htm> or <ftp://wbar.uta.edu>.
	 
Common Principal Components (CPC) is a data analysis technique created by
Bernhard Flury that allows two or more matrices to be compared in a
hierarchical fashion. The ideas are most completely presented in Flury (1988),
Common Principal Components and Related Multivariate Methods (Wiley, New York).

The software is likely to be useful to a variety of people, but especially
evolutionary biologists and ecologists who are interested in comparing the
pattern of covariation among traits between populations.  This particular
package is based upon Flury's work, which assumes multivariate normal data.  A
more general approach utilizing resampling methods will be released soon (see
http://www.uta.edu/biology/phillips/software.html).  The current program is
most suitable for phenotypic data, although genetic data such as family or
strain means can also be used.  Subsequent programs will also allow the
analysis of simple quantitative genetic breeding designs (these programs are
currently in beta-test).

Compiled versions are available for various flavors of DOS/Windows, Macintosh,
and several UNIX platforms.  Contact me if you need other versions.

More details are available in the readme file

You may also be interested to visit the EP-GED database, which has a
collection of software useful for evolutionary biology and population
genetics <http://wbar.uta.edu>.
