3 Summary FSL Mask Extraction 17 FSL software license and complete personal information including institution and operating system used. A new page will be displayed where it is possible to download a python file fslinstaller.py containing the newest version of the software. To proceed with the installation, just open command line and type the following for both MacOS and Linux (with specified installation directory): Note: FSL requires X11 windowing system, XQuartz . For Windows users, the procedure might be more complex and require a Subsystem for Linux (Windows 10 only) or a version of FSL running on virtual Linux machine downloadable here . After everything is set up, we can start looking at one specific case we might need this software for! We will explore one application of FSL: mask extraction . This can indeed be used as solid ground for more complex pipelines which include DL networks for specific aims (e.g. generating attenuation correction maps for brain-pet MR). Case study "This can indeed be used as solid ground for more complex pipelines which include DL networks for specific aims" Let’s first familiarise with the FSL software. It can be called from terminal through simply typing the command FSL which should generate the window in Figure 1. From here, you can access several different tools available within the platform. Instead, we will proceed with the brain extraction through terminal. In order to generate a brain from a structural image of the brain, we can simply type the following commands: cd ~/Downloads python fslinstaller.py -d /usr/local Figure 1
