It is a necessary part of reading your data. <h3>I'm still confused. How can I learn more information about FSL?</h3> The [FSL website][1] has a few different options for learning more about the program, including a detailed [PowerPoint][2] that explains how to use FSL step-by-step as well as why it's important to know. <h3>How do I install FSL?</h3> To install FSL, follow the directions listed [here][3].
