PHAST

You can either download the Phast binaries or compile Phast from source. Binaries are generally the easiest way to get up and running with Phast and are suggested for new users.

PHAST is written in standard C and should compile cleanly on any standard UNIX platform (including Mac OS X). PHAST is mostly self-contained, but it does depend on the LAPACK package for certain matrix operations (diagonalization and inversion). On Mac OS X (version 10.3 or later) LAPACK is built-in, but on other platforms, the C port of LAPACK, called CLAPACK, must be installed for PHAST to be fully functional.

PHAST binaries for Windows, MacOSX, and Linux can be downloaded from here.

Compiling PHAST from Source

MacOSX

 1. Download a copy of Phast from here and extract the file phast*.tgz using 'tar -xvzf phast*.tgz'
 2. Change directory to 'phast/src/' and run the command 'make'
 3. The Phast binaries should be located in the 'phast/bin/' directory.

Linux

Part 1 - Installing Clapack - (If you already have Clapack installed, skip to Part 2)
 1. Download Clapack from the following URL http://www.netlib.org/clapack/clapack.tgz
 2. Unzip clapack.tgz with the command 'tar -xvzf clapack.tgz'
 3. Go into the newly created Clapack directory (i.e. 'cd CLAPACK-3.2.1') and type 'cp make.inc.example make.inc && make f2clib && make blaslib && make lib'
Note: Building Clapack can take several minutes depending on your system

Part 2 - Installing Phast
 4. Download a copy of Phast from http://compgen.cshl.edu/phast/ and extract the contents of phast*.tgz using 'tar -xvzf phast*.tgz'
 5. Change directory to 'phast/src/' and run 'make CLAPACKPATH=/usr/local/software/clapack' replacing '/usr/local/software/clapack' with the path of your Clapack install (e.g., CLAPACKPATH=/home/username/CLAPACK-3.2.1)
 6. The Phast binaries should be created in the '../bin/' directory

Windows

 PHAST can be compiled under Windows using the Cygwin linux-like environment, but some users have reported difficulties in making this work. We recommend using the provided binaries for Windows, unless you have a good reason to compile the package from source.
