Note -- you need the sources and documents in some form, in order to have the documentation, even if you do not intend to recompile the source code. Most Windows, Mac OS X, Mac OS and Linux users will want to use the executables for their machines, but all will need the documentation as well. Whenever PHYLIP is packaged as a single archive, it does include the documentation.

The Windows executables, documents, and sources are in the form of self-extracting archives. To extract them, put them in a directory by themselves and then run them as programs. They will unpack themselves into the many files of the package. This may not work on Windows Vista, and if so, we have instead provided a ZIP archive that can be unpacked by the built-in zip-archive extraction when downloaded to Vista. The Mac OS X package is distributed as a .dmg Disk Image which can be unpacked using the instructions on our installation web page. The Mac OS 9 archives will (hopefully) be automatically unpacked when they are transferred. The Linux executables can easily be compiled after downloading the source code.

What to do

First note that at the bottom of this page are a link to register your copy of PHYLIP, and a link to installation instructions. To transfer the files, click on the appropriate links below. Then register, and read the installation instructions and follow them.

1. Fetch the following:

Linux or Unix

For Linux or Unix (or other systems that need to compile from source code):

gzip'ed tar archive of C sources and documentation

(see below for information on how to compile these, and for information on precompiled Linux and Unix executables).

Windows

We have here the PHYLIP 3.69 package for Windows 3.1, Windows NT, Windows 98, Windows 2000, Windows xp and Windows Vista, in a variety of forms. You will not need most of these, so read carefully before downloading. If you click on one of these selections to download it, make sure your browser saves it to disk. After downloading, but before you do anything else, you should read our installation instructions. You will probably want to do one of these:

If you want to put PHYLIP onto a Windows system, and you can transfer a file that is about 3 megabytes in size, you will want this self-extracting archive:
self-extracting archive of PHYLIP 3.69 for Windows. (It should work now, even with Windows Vista).
If you have a Windows Vista system that refuses to let the self-extracting archive self-extract, or if you have some other Windows system that will not let you download or self-extract that file, but it can transfer a file that is about 3 megabytes in size, you will want to download this zip archive, and then right-click on it to see an option to unzip the archive:
Zip archive of PHYLIP 3.69 for Windows.

Mac OS X

For Macintosh Mac OS X (either Intel iMac or PowerMac) the package is distributed as a single compressed disk image (.DMG) file of 6 Megabytes. Note that this may not be readable on Mac OS X 10.0 systems which do not allow disk image files to be compressed, but it should be readable on all later versions of Mac OS 10. Download this file:

Documentation, source code and executables

Mac OS 8 or 9

Note -- We have not attempted to compile the latest versions to make Mac OS 8 and Mac OS 9 executables, so for the moment the executables available here are still version 3.65.

For Macintosh Mac OS (Mac OS 8 or 9) the package is distributed as a single Stuffit (.sit) archive of 4.9 Megabytes, which contains the source code, documentation, and executables:

Executables, Documentation and C source code

If the Mac OS machine on which you will use the package is not connected to the Internet, you may instead prefer to download these four Stuffit archives which are each small enough to be written onto a floppy disk:

2. Register your copy

(It is not necessary to register separately for each file transferred -- you can register once after downloading several files).

3. Install PHYLIP

Here you will find more information about how to install PHYLIP on your computer once you have fetched the appropriate archive files.

Precompiled executables available elsewhere

Debian linux executables

Andreas Tille and Stephane Bortzmeyer have compiled and made available a set of PHYLIP 3.69 executables for Debian Linux. These are in the "unstable" section of Debian packages and may be downloaded for free ("free in the sense of free beer") from its page on the Debian web site at http://packages.debian.org/unstable/science/phylip. or from various Debian mirror sites. Of course, one can also install the source code (see under Unix above) and compile it yourself.

Executables for FreeBSD

A PHYLIP 3.69 package for FreeBSD Unix is available, thanks to David Bader and others. It is located at the BSD PHYLIP package web page at http://www.freebsd.org/cgi/cvsweb.cgi/ports/biology/phylip/.

Specialized source code versions available elsewhere

Source distribution for NetBSD

A set of sources for PHYLIP 3.61 for the NetBSD operating system has been produced by Marc Baudoin. They are available from The NetBSD Packages Collection PHYLIP page at ftp://ftp.netbsd.org/pub/NetBSD/packages/pkgsrc/biology/phylip/README.html. They are not available there as executables, but rather as source code set up to be automatically compiled on NetBSD.
