| = Tutorials = == Important notes == * Distribution: * In all the tutorials, we will consider that you are working with the source distribution of Brainstorm, as it is the recommanded way to use this toolbox. * If you are working with compiled binaries, some menus might be missing, but everything else should work the same way. * Before starting using Brainstorm with your own data: * You should go through '''__all the tutorials__''' in the following section: "''Getting started with Brainstorm''". In just a few hours, they will introduce you to most of the main features of the application. * Then you can read more specific tutorials, closer to your personal interests. |
= Brainstorm Tutorials = The following pages will take you through a typical workflow of data analyses that will feature most of the tools and applications of Brainstorm. We are updating these pages constantly, keeping up with new developments and features in the software. You are therefore welcome to suggest improvements and additions but also to contribute by becoming an editor of this wiki. Please [[mailto:brainstorm@sipi.usc.edu|email us]] if you would like to contribute. |
