Dear TAXACOM subscribers:
Please note that RASA version 2.2 software for measuring phylogenetic
signal and data analysis has been uploaded and can be downloaded
at the following URL as a binhexed, self-extracting archive:
http://loco.biology.unr.edu/archives/rasa/rasa.html
and by anonymous ftp at
loco.biology.unr.edu (pub) (rasa)
This software (for Mac only) corrects a serious bug in the power&effect
analysis option in RASA 2.1. Please pass this announcement along to any
user you may know who might not be a subscriber to TAXACOM.
RASA 2.2 also offers two null hypothesis formulations: the original,
analytical, equiprobable null and a new permutation null that provides a
better fit of the test to the student-t distribution.
Other features include:
a tool for the detection of otherwise cryptic long edge taxa, which cause
inconsistency of methods of tree-building. This tool (the taxon variance
plot) was recently described in
Lyons-Weiler, J., and G.A. Hoelzer. 1997. Escaping from the
Felsenstein Zone by detecting long branches in phylogenetic data.
Molecular Phylogenetics and Evolution 8:375-384.
a test for the suitability of outgroup taxa for rooting trees, to be
described in
Lyons-Weiler, J., G.A. Hoelzer and R.J. Tausch. 1998. Optimal
Outgroup Analysis. Biological Journal of the Linnean Society
(in press).
new experimental treatments of phylogenetic data, including a type of
waveform analysis that reveals structure in biological sequences
