This message announces the release of Random Cladistics 3.0, software
designed for performing a variety of randomization-based data
manipulations in the field of phylogenetic inference.
It is available free via anonymous ftp to zoo.toronto.edu (or
zoo.utoronto.ca) in the directory "pub" as the self-extracting DOS
utility "random.exe", please transfer in binary mode.
1) "slipshod" - as per bootstrap but by marking scopes (i.e., strings
of contiguous characters) for inclusion/exclusion - output includes
data on frequency of clade support (as per bootstraps), as well as
a table of effects of inc/exclusion of regions on length/RI/#trees.
2) JOYRIDE - random-addition sequence replicates for avoiding islands
or penninsulae of trees - output includes all most-optimal trees
found as well as table of performance in each attempt.
3) TRECMP - relatively versatile option for comparing one tree with many
saved in a treefile, for looking for how frequently two or more
clades appear SIMULTANEOUSLY in bootstrap replicates (in fact you can
look for the whole of a tree), for assessing levels of tree-balance,
etc etc etc
4) MUCH improved on-line help on RC and on Hennig86 including menubars
and word-searches etc.
5) TORA - for converting Hennig86 or #nexus format files for input to
Farris' Rapid-Nucleotide-Analysis (RA) program.
6) Taxon Jacknifing including JMI clade support values now accepts
matrices of any size like the rest of the algorithims.
THINGS RC 2.1 did and 3.0 still does:
1) regular old bootstrapping
2) other kinds of character-manipulation like deltion
5) PCP - confidence in coevolution.
