Brownie is a program for analyzing rates of continuous character evolution on a tree or set of trees. See http://www.brianomeara.info/brownie for more info.

There is also a development version implementing many of the new methods described in my dissertation (available from Nature Precedings). Note that this is still being actively coded (see changes here) and the methods have not all been peer-reviewed yet and so are unavailable for general use.

Funding for its development has come from a University of California, Davis Population Biology fellowship, NSF Graduate Research Fellowship and Dissertation Improvement Grant (DEB-0608487) awards to Brian O'Meara, and from the National Evolutionary Synthesis Center (NESCent) (NSF #EF-0423641).
