FSL Install Script

The fslinstaller.py script carries out the installation of FSL, configuring your environment to enable you to run FSL from your terminals.

if you use Mathworks' MATLAB it will configure your startup.m file to allow you to use the FSL MATLAB functions and on OS X platforms it will also install FSLView into /Applications.

Running the installer (on Mac or Linux)

Administrative privileges may be required

Installation into certain folders on your computer (eg the default, /usr/local) may require administrative privileges. If this is the case, the installer will attempt to gain these privileges through the use of the sudo command, which will require you to enter your password for verification. If you don't have any rights to use sudo (an administration account on OS X) then the installer will fail and will need to be run as the root user. Should you install as root see the configuring your account for FSL section for details on how to use the installer to setup your user account for FSL.

The installer requires access to the internet to be able to download the FSL software appropriate for your platform and runs from within a terminal session, so you need to open a terminal:

Linux (Centos)
- The Terminal application can be found in Applications > System Tools > Terminal menu
Mac
- The Terminal application can be found in /Applications/Utilities

In the terminal change to the folder containing the downloaded file and run it; assuming that you wish to install into /usr/local (the default) then just press the Return key when the installer asks where to install to. For example if you downloaded to your Downloads folder:

cd ~/Downloads
python fslinstaller.py

Once the install completes Linux users should log out (System > Log out) and log back in to complete the FSL setup. If you are accessing the Linux computer via a remote SSH session then close the SSH session and re-login. Apple OS X users should open a new terminal window to begin using FSL.
