David Swofford
of the School of Computational Science and Information Technology, Florida State University, Tallahassee, Florida has written PAUP* (which originally meant Phylogenetic Analysis Using Parsimony). PAUP* version 4.0beta10 has been released as a provisional version by Sinauer Associates, of Sunderland, Massachusetts. It has Macintosh, PowerMac, Windows, and Unix/OpenVMS versions. PAUP* has many options and close compatibility with MacClade. It includes parsimony, distance matrix, invariants, and maximum likelihood methods and many indices and statistical tests. It is described in a web page athttp://paup.csit.fsu.edu/
, which also contains links to
its web pages at Sinauer Associates.
It is available for the following types of systems:
lecturerservices (at) palgrave.com
.
For New Zealand, Korea, Japan, Brazil and Australia see the addresses at
this web page.
Derek Sikes of the University of Alaska Mueum, Fairbanks, Alaska
(ffdss (at) uaf.edu) and Paul
Lewis of the
Department of Ecology and Evolutionary Biology of the University of Connecticut
have produced PAUPRat, a program that generates a text file
which can be used as commands by PAUP*
to have it carry implement Kevin Nixon's highly effective
tree search method, the Parsimony
Ratchet. The input files for PAUPRat can also
be modified to implement Rutger Vos's
comparable Likelihood Ratchet. It is available as Mac OS,
Mac OS X and Linux executables, as a DOS executable that can be run under
Windows,
and in source code, from
its web site
at http://users.iab.uaf.edu/~derek_sikes/software2.htm.
MacClade is a pioneering program for
interactive analysis of evolution of a variety of character types,
including discrete characters and molecular sequences. It works on
Macintoshes with Mac OS X, up to and including
now Leopard, Mac OS X version 10.6 (and also on Mac OS).
MacClade enables you to use the mouse-window interface to specify and
rearrange phylogenies by hand, and watch the number of character steps and the
distribution of states of a given character on the tree change as you do so.
It has many other features beyond this, including ability to edit data,
print out phylogenies, and even simulate the evolution of data on a tree.
MacClade was written by Wayne Maddison (now of the Department of Zoology, University of British Columbia)
and David Maddison of the Department of Entomology,
University of Arizona. Until 2011 it was distributed commercially by
Sinauer Associates of Sunderland, Massachusetts, USA.
As MacClade will not function with the forthcoming Mac OS X 10.7 (Lion),
the Maddisons have made it available as a free download. It is
available at the MacClade web site
starting with version 4.08a. It includes a manual.
An much earlier and less capable Version, 2.1 (which for example
cannot read nucleic acid sequences and has many fewer features for discrete
characters) is also available as a Mac OS 9 executable from the EMBL and Indiana
molecular biology software servers at (respectively)
J. S. Farris
iubio.bio.indiana.edu
, and ftp.ebi.ac.uk
, in directories
molbio/mac
and pub/software/mac
,
respectively, as a BinHexed and squeezed archive, (respectively
macclade-old.hqx
and macclade21.hqx
. A demo
version of MacClade 3 that will not save or print files
is also available there.
akluge (at) umich.edu
) and by Diana Lipscomb at
George Washington University (biodl (at) gwuvm.gwu.edu
). It runs on PC-compatible
microcomputers with at least 512K of RAM and needs no math coprocessor or
graphics monitor. It can handle up to 180 taxa and 999 characters.
It was described in the paper:
Farris, J.S. 1989, Hennig86: a PC-DOS program for phylogenetic analysis.
Cladistics 5: 163.
Mark Siddall
, Assistant Curator of Annelida at the American Museum of Natural History, New York (siddall (at) amnh.org
) has released Random Cladistics, version 4.0.3, a set of programs that can carry
out bootstrapping, jackknifing, a variety of kinds of permutation tests, and
search for "islands" of trees,
using Hennig86 or
NONA to analyze the data. It can also
mark ranges of sites for
inclusion or exclusion, compare trees from the analyses, compute an index
of incongruence between data sets, and do many other
operations. To use it you must have a copy of Hennig86
(for whose distribution see above). Random Cladistics will carry out the
appropriate transformations of your data and will call Hennig86 and have it
analyze them, and then it will summarize the results.
Random Cladistics is described by its author as no longer being supported
software -- he says that "Winclada
is far superior and provide's a nice interface."
Random Cladistics and associated programs are still distributed by their author
from its web site at
http://research.amnh.org/~siddall/rc.html
as MSDOS executables.
Torsten Eriksson
of the Bergius Botanical Garden, Stockholm, Sweden (torsten (at) bergianska.se
)
has written a program, AutoDecay which
generates Decay Indices from an existing PAUP* 4.0 treefile. It is intended
to simplify the the task of
creating reverse constraint trees in PAUP* 4.0 and subsequent generation of
Bremer support values. (Bremer, K. 1994. Cladistics 10: 295-304).
AutoDecay version 5.06 is written in the scripting language Perl, and runs on
most systems that have Perl installed. Autodecay can
be obtained from
Eriksson's software web page from
http://www.bergianska.se/index_forskning_soft.html
.
Doug Eernisse
of the California State University, Fullerton (DEernisse (at) fullerton.edu
)
has constructed DNA Stacks version 1.3.5, a Macintosh HyperCard stack
that can carry out a variety of analyses on DNA sequences. It
does not do phylogenies itself. It has an alignment editor, and can
carry out various kinds of translation,
and codon bias analysis. It can write out data sets in PAUP*, Hennig86, and
PHYLIP formats. It is included here because in its
"Support Index Blocks..." menu item it is able to prepare jobs for
PAUP* to enable Decay Index (Support Index) analysis.
It is available
by World Wide Web from
http://biology.fullerton.edu/deernisse/dnastacks.html
.
Michael Sorenson
of the Department of Biology, Boston University (msoren (at) bu.edu) has released TreeRot, version 3, a program that helps make Bremer Support Indices ("decay indices") for parsimony analyses. It generates a PAUP* command file with a constraint statement for each node in a given shortest or strict consensus tree and with commands to search for trees inconsistent with each of these constraint statements in turn. For nodes with decay indices of more than a few steps, the constraint statement approach is much more effective than simply finding all trees 1, 2, 3, 4, etc. steps longer than the shortest tree and then examining their strict consensus for which nodes are lost. This version also supports the determination of partitioned Bremer support indices introduced in the paper: Baker, R.H., and R. DeSalle. 1997. Multiple sources of character information and the phylogeny of Hawaiian Drosophilids. Systematic Biology 46: 654-673, and it will also parse the PAUP* log file, automatically calculating the decay index for each node. It is written in the Perl scripting language, and a Mac OS Macintosh executable is also available. Both are distributed at its web site at http://people.bu.edu/msoren/TreeRot.html.
J. S. Farris
has written RA (Rapid nucleotide Analysis). It features rapid bootstrapping. It is available from Arnold Kluge, Amphibians and Reptiles, Museum of Zoology, University of Michigan, Ann Arbor, Michigan 48109-1079, U.S.A. (akluge (at) umich.edu
)
and Diana
Lipscomb at George Washington University (BIODL
(at) gwuvm.gwu.edu
) who may
be contacted for details. The cost is said to be about $30 US.
Kevin Nixon
of the L. H. Bailey Hortorium at Cornell University in Ithaca, New York (kcn2 (at) cornell.edu) has written WINCLADA version 0.9.99m24, an interactive program that can read and edit trees and data files, display character state changes inferred by parsimony on diagrams of the trees, and launch runs of the programs NONA, PIWE, and Hennig86. WINCLADA is available as a Windows95/98/NT executable from its web site athttp://www.cladistics.com/about_winc.htm
. It is available on
a shareware basis: the user who downloads it must pay $50 to Kevin Nixon at
Winclada/Kevin C. Nixon, 2210 Ellis Hollow Road, Ithaca, New York 14850.
There is also a $200-per-class fee for its use in courses.
WINCLADA supersedes and combines features of Nixon's earlier programs
ClaDOS and DADA, which are no longer distributed.
Pablo Goloboff,
of INSUE - Fundación e Instituto Miguel Lillo 205, 4000 S. M. de Tucumán, Argentina (instlillo (at) infovia.com.ar with Subject line "para Pablo Goloboff") has written NONA (Noname), version 2.0, PiWe (Parsimony with Implied WEights), and SPA to carry out parsimony including weighted parsimony analyses. NONA searches for most parsimonious trees according to character weights defined by the user a priori. Pee-Wee calculates weights of the characters by a method introduced by Goloboff, a noniterative version of J. S. Farris's "successive weighting". It was described in Goloboff's paper in Cladistics 9: 83-91, 1993. SPA is a generalized parsimony program that allows differential weighting of changes between different states. NONA is said to be faster than other parsimony programs. A Windows version of NONA which includes Piwe and SPA is available as freeware from its web page athttp://www.cladistics.com/aboutNona.htm
.
Pablo Goloboff,
of INSUE - Fundación e Instituto Miguel Lillo 205, 4000 S. M. de Tucumán, Argentina, (pablogolo (at) csnat.unt.edu.ar) together with J. S. Farris of the, Laboratory of Molecular Systematics of the Naturhistoriska Riksmuseet, Stockholm, Sweden and Kevin Nixon of the L. H. Bailey Hortorium, Cornell University, Ithaca, New York, have produced TNT (Tree analysis using New Technology), version of August 2008. This is a parsimony program intended for use on very large data sets. It makes use of the methods for speeding up parsimony searches introduced by Goloboff in the paper: Goloboff, P.A. 1999. Analyzing large data sets in reasonable times: solutions for composite optima. Cladistics 15: 415-428, and the highly effective "parsimony ratchet" search strategy introduced by Nixon in the paper: Nixon, K.C. 1999. The parsimony ratchet, a new method for rapid parsimony analysis. Cladistics 15: 407-414. It can handle characters with discrete states as well as continuous characters. The program is distributed as Windows, Linux, and both PowerMac and Intel Mac OS X executables. The program and some support files including documentation is available from its web page athttp://www.zmuc.dk/public/phylogeny/TNT
It is free, provided you agree to a license with some reasonable limitations.

Xuhua Xia
of the Department of Biology and the Center for Advanced Research in Environmental Genomics (CAREG) of the University of Ottawa, Ontario, Canada (xxia (at) uottawa.ca
) has released DAMBE
(Data Analysis in Molecular Biology and Evolution), version 5.0.25,
a general-purpose package for DNA and protein sequence phylogenies,
and also gene frequencies. It can read and
convert a number of file formats, and has many features for
descriptive statistics. It can compute a number of commonly-used
distance matrix measures and infer phylogenies by parsimony, distance,
or likelihood methods, including bootstrapping (by sites or by codons)
and jackknifing. There are
a number of kinds of statistical tests of trees available, and many other
features. It
can also display phylogenies. DAMBE includes a copy of ClustalW; there is also code from
PHYLIP.
An interesting feature is a simple web browser that allows sequences to
be fetched over the web while running DAMBE.
DAMBE is described in two publications, a paper and a book:

John Czelusniak
, then of the Department of Anatomy and Cell Biology, Wayne State University, Detroit, Michigan wrote sog, a C program demonstrating an algorithm to find the most parsimonious phylogeny along with the parsimony strength of grouping (or Bremer decay index) for nucleotide sequences in one pass of a branch and bound algorithm. This differs from the implementation in PAUP* which uses a separate branch and bound search to find the strength of grouping for each group in the tree, using the tree group exclusion option. John said (some time ago) that "sog is a rather ugly hack which will be optimized and streamlined. It IS ALPHA SOFTWARE, which means it has not been tested extensively on datasets other than our primate datasets." It is available at the IUBIO archive athttp://iubio.bio.indiana.edu/soft/molbio/evolve/
.
It is distributed as generic C source code which should be able to compile
and run on any system that has a C compiler.
Rino Zandee
(rino.zandee (at) gmail.com
)
formerly of the Institute of Evolutionary and Ecological Science, Van der Klaauw
Laboratory, Leiden University, has written CAFCA version 1.5.12,
the Collection of APL Functions for Comparative
Analysis. It carries out a
search for the most parsimonious tree with discrete-character data (either
two-state or multistate), using a search for cliques of component
compatibility (monothetic subsets) to propose the candidates for most
parsimonious trees. The program is written as functions in the APL language,
but PowerPC Mac OS (or maybe it's Mac OS X) executables are distributed. The program is
free and is available from the
CAFCA Web Site

Daniel Barker
(db60 (at) st-andrews.ac.uk
)
of the University of St. Andrews, Scotland, U.K.,
has written LVB version 3.1,
a program for inferring phylogenies using parsimony and simulated annealing.
Simulated annealing is intended to allow searches for most parsimonious trees
with large numbers of species.
It is described as often giving good results with large matrices. Up to
16383 objects and 32766 characters may be used. Aligned nucleotide sequences
with ambiguous nucleotides and/or discrete morphological characters can be used.
Bootstrapping of the data is also supported.
The program is currently available in ANSI C source code as a Unix tar file,
and as executables for Windows, Mac OS X, and Linux.
The text of a manual
can also be read or downloaded from the web site.
LVB is available from its Web site at

Web server
from the Institut Pasteur.
Dick Hwang
of the Department of Genome Sciences, University of Washington (dhwang (at) u.washington.edu)
has written GAPars, a program using a genetic algorithm to search for
most parsimonious phylogenies. The program is written in C++ and should
compile on Unix C++ compilers and on most other C++ compilers. He describes
it as working "rather inefficiently" and "not ready for prime-time use".
It can be obtained by emailing Hwang at the address above.

Rod Page
(r.page (at) bio.gla.ac.uk
), of
the Division of Environmental and
Evolutionary Biology of the University of Glasgow has released
GeneTree, version 1.3.0,
a program that produces "reconciled trees" that fit a tree of gene copies to
a species tree. It uses a parsimony criterion where the penalty is the
number of deletions and duplications required to reconcile the gene tree with
the species tree. The program is described as "preliminary". The program
is described in the paper: Page, R. D. M. 1998. GeneTree: comparing gene and
species phylogenies using reconciled trees. Bioinformatics 14:
819-820, and its algorithm is described in the paper:
Page, R. D. M. and M. A. Charleston. 1997. From gene to organismal phylogeny:
Reconciled trees and the gene tree/species tree problem. Molecular Phylogenetics and Evolution 7: 231-240.
It is available as a Macintosh executable and as an executable for
Windows. They are
available from
the GeneTree web site at

.
A manual is also available online there.
John Huelsenbeck
(johnh (at) berkeley.edu) of the Department of Integrative Biology, University of California, Berkeley released CodonBootstrap version 3, now distributed by Jonathan Bollback. This is a utility that will generate non-parametric bootstrap data sets from a DNA sequence file. The program re-samples codons to (1) avoid problems when analysing data under models that assume coding structure (e.g., rates partitioned by sites), or (2) when the user wishes to re-sample sites and maintain the original autocorrelation among positions within the codon. CodonBootstrap is available as a C source code that can be compiled for Unix from Jonathan Bollback's software web page at http://www.simmap.com/bollback/software.html. A Macintosh version that was formerly distributed seems not be available any more.
Mark Clement, David Posada, and Keith Crandall of the
Universidad Vigo, Spain (Posada) and the Department of
Zoology, Brigham Young University, Provo, Utah (dposada (at) uvigo.es)
have released TCS version 1.21, a program for
estimating gene genealogies within a population. It does so by using the
method introduced in the paper: Templeton, A. R., K. A. Crandall and
C. F. Sing. 1992. A cladistic analysis of phenotypic associations with haplotypes inferred from restriction
endonuclease mapping and DNA sequence data. III. Cladogram estimation.
Genetics 132: 619-633.
This is a method that connects existing haplotypes in a minimum spanning
tree which is essentially a parsimony method. It can also infer
networks with loops in them.
TCS is written in Java and has a graphic user interface for the
display of the resulting networks. It may be run on any system that has the Java
runtime environment. The program is described in the paper:
Clement M., D. Posada, and K. Crandall. 2000. TCS: a computer program to
estimate gene genealogies. Molecular Ecology 9: 1657-1660.
It implements the estimation of the 95% parsimony
connection limit, and the estimation of outgroup weights (which
are used to designate the root of the tree). It takes as input
sequence files in NEXUS or PHYLIP format, and accepts absolute distances
between sequences as input.
The output is a Postscript picture of the tree, which can be saved as a
Postscript file.
TCS is available as Java executables, with documentation, at
its web site
at http://darwin.uvigo.es/software/tcs.html
.
David Posada (dposada (at) uvigo.es), of the
Universidad Vigo, Spain, Keith Crandall, of the Department of Zoology,
Brigham Young University, Provo, Utah (Keith_Crandall (at) byu.edu)
and Alan Templeton, of the Department of Biology of Washington University, Saint
Louis, Missouri (temple_a (at) biology.wustl.edu) have made available
GEODIS (version 2.6).
It implements Templeton's method of Nested Clade Analysis, which
is intended to distinguish between historical divergence of populations
and geographical separation, using the geographical distribution of
haplotypes in a genealogy. GEODIS is a Java program which can run on
any platform. It is described in a paper: Posada D., K. A. Crandall and
A. R. Templeton. 2000. GeoDis: A program for the cladistic nested analysis of
the geographical distribution of genetic haplotypes. Molecular Ecology
9: 487-488. It is available at

Jon Jeffery
(jon (at) donnasaxby.com), then of the Insitute of Biology, Leiden University, The Netherlands has written Parsimov, a series of Perl scripts to implement "event cracking", a parsimony-based method of finding the minimum number of changes in developmental sequences of events that are necessary to explain the evolution of pairs of characters on a tree. Among the uses of this method is to reconstruct ancestral developmental sequences. The programs include:http://www.uni-oldenburg.de/molekularesystematik/en/34011.html#EvoDevo
David Swofford, of the Center for Evolutionary Genomics, Duke University, Durham, North Carolina, together with Stewart Berlocher of the Department of Entomology of the University of Illinois, Urbana, Illinois wrote Freqpars. It implements parsimony analysis based on gene frequencies. The method was described by D. L. Swofford and S. H. Berlocher in a paper in Systematic Zoology 36: 293-325, 1987. The program is available in FORTRAN 77 source code. The search for most parsimonious trees under Swofford and Berlocher's criterion is not very extensive, Swofford notes, because the individual tree evaluations are computationally difficult. The source code in FORTRAN, with documentation, has been made available (after a period of unavailability) at Swofford's PAUP web site as one of a number of "companion applications".
