.. _TBSS_01_Download_Install.rst: ============================= TBSS #1: Download and Install ============================= -------- Before you Begin **************** TBSS comes with the `FSL software package `__, which is covered in a :ref:`previous tutorial `. If you haven't used FSL before, I recommend reviewing that module to become familiar with it; the following chapters assume that you know how to use basic FSL commands, as well as the FSL viewer, `FSLeyes `__. Installing FSL -------------- FSL can be installed on different operating systems, such as Windows, Macintosh, and Linux. The Windows version requires a virtual machine to run FSL. This course will assume that you have a Macintosh or Linux operating system, and the tutorials will be recorded using an iMac desktop. The instructions for installing FSL on different operating systems can be found `here `__. The instructions are detailed and will not be repeated here; but for those who are using a Macintosh computer, a screencast can be found here to walk you through the installation and setup: `FSL Installation Video Walkthrough `__. .. warning:: You may come across the following error when running fslinstaller.py: [FAILED] [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:661). In that case, try running the installer by specifying the absolute path to your python command, e.g.: ``/usr/bin/python fslinstaller.py``. Video ----- A demonstration of how to install FSL can be found `here https://youtu.be/E9FwDCYAto8?t=16>`__. Next Steps ********** When you have installed FSL, you will need a sample dataset to analyze. To see how to download that data, click the `Next` button.
