    For Windows:
  1. Download the latest version of the Java Runtime Environment at www.java.com. (It's a good idea to make sure the JRE_HOME environment variable is set to its location before running Path2.)
  2. Please download PLINK from the following website: http://pngu.mgh.harvard.edu/~purcell/plink/download.shtml and install it on your machine. Make sure to include the location of the PLINK executable file in your PATH environment variable. Path2 supports version v1.07 of PLINK (built 10/Aug/2009).
  3. Download a Perl distribution for Windows, for example: (It’s a good idea to test it out after the install by running "perl --version" (without the quotes) from a terminal.)
  4. You will also need R, which can be found here.
    Debian-like Linux (for example, Ubuntu):
  • Use a graphical package manager, or: apt-get install openjdk-6-jre perl plink r-base-core
