PLINK: Whole genome data analysis toolset

A PLINK tutorial

These notes are designed to help Windows users who are unfamiliar with the command line to set up the example files for the tutorial.

Go to the start menu and select the "Run..." option

Type "cmd" at the prompt.

This should bring up a command window (i.e. this is MS-DOS). Using the command line, create a new folder for the tutorial files. In this case, I've first moved to the drive called "E" by typing

You might not have a drive called E: -- your default drive is probably C:. The exact location of where you run this tutorial is not important -- we are next going to create a folder, but this can be anywhere on your system.

By typing (all on one line)
mkdir example

we have created a new folder called example (assuming this did not already exist). Move into this new folder with the cd command: (all on one line)
cd example

Finally, using Windows, copy the file you downloaded to this folder and unzip, e.g. using WinZip as below. If you do not have WinZip installed, you can obtain a free evaluation copy from the product's website


You now should return to the command line prompt, which will still be point to the newly created directory, with the required PED and MAP files in it. You can verify this by typing at the command line:

which should show 4 new files in addition to the zip archive:
      Volume in drive E is New Volume
      Volume Serial Number is XXXX-XXXX

      Directory of E:\example

You can erase the ZIP file with this command:

You are now ready to return to the main tutorial.
