+Downloading f-ASL
+===============
+
+f-ASL (functional ASL) is a software package written by `Luis Hernandez-Garcia <http://web.eecs.umich.edu/~hernan/>`__. You can download the package by clicking `here <http://web.eecs.umich.edu/~hernan/Public/Programs/>`__ and clicking on the **LuisTools.tar** button.

+.. figure:: Download_fASL.png
+
+
+.. note::
+    You will need to have Matlab installed to run f-ASL. Most universities can give you a license for free; ask your local IT person for more information.
+
+
+After you have downloaded the LuisTools file, in your Downloads you should see a file called ``LuisTools.tgz``. Either expand this file by double-clicking on it, or navigating to it with a Terminal and typing the following:
+
+::
+
+    tar -xzf LuisTools.tgz
+
+
+This will create a folder called LuisTools.
+
+
+Setting the Path
+----------------
+
+In order to use f-ASL from anywhere on your computer, you will need to set a path pointing to the f-ASL libraries. If LuisTools is in your Downloads directory, for example, open up Matlab and then type:
+
+::
+
+    addpath ~/Downloads/LuisTools
+
+
+You will then be able to open up f-ASL by typing ``fasl01`` and pressing Enter.

+
+    If you have downloaded and set the path to the f-ASL toolbox correctly, you should see this GUI when you type ``fasl01`` at the Matlab command line.

+Now that you have f-ASL installed, we will use it to analyze a sample ASL dataset. (Need to find a suitable open-access ASL dataset and then point to it)
