PHYLIP - Phylogeny Inference Package (version 3.6)
|
|
|
|
PHYLIP (the PHYLogeny Inference Package) is a package of programs for
|
|
inferring phylogenies (evolutionary trees). Methods that are
|
|
available in the package include parsimony, distance matrix, and
|
|
likelihood methods, including bootstrapping and consensus trees. Data
|
|
types that can be handled include molecular sequences, gene
|
|
frequencies, restriction sites, distance matrices, and 0/1 discrete
|
|
characters.
|
|
|
|
The programs are controlled through a menu, which asks the users which
|
|
options they want to set, and allows them to start the
|
|
computation. The data are read into the program from a text file,
|
|
which the user can prepare using any word processor or text editor
|
|
(but it is important that this text file not be in the special format
|
|
of that word processor -- it should instead be in "flat ASCII" or
|
|
"Text Only" format). Some sequence analysis programs such as alignment
|
|
programs can write data files in the PHYLIP format. Most of the
|
|
programs look for the data in a file called "infile" -- if they do not
|
|
find this file they then ask the user to type in the file name of the
|
|
data file.
|
|
|
|
Output is written onto special files with names like "outfile" and
|
|
"treefile". Trees written onto "treefile" are in the Newick format, an
|
|
informal standard agreed to in 1986 by authors of a number of major
|
|
phylogeny packages.
|
|
|
|
PHYLIP is the most widely-distributed phylogeny package, and competes
|
|
with PAUP to be the one responsible for the largest number of
|
|
published trees. PHYLIP has been in distribution since 1980, and has
|
|
over 6,000 registered users.
