| = Tutorials = == Important notes == * Distribution: * In all the tutorials, we will consider that you are working with the source distribution of Brainstorm. * If you are running a stand-alone distribution: some menus might be missing, some indications might not applicable to you, 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. * If you want a printed version of this documentation: * Open a tutorial, go to the menu on top of the page, * Select ''More actions > Print view'', print the page, and go to the next tutorial. |
= 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. |

| == Getting started with Brainstorm == === Dataset description === The dataset that will be used for tutorials #2 to #10 is a somatotopy experiment recorded with a CTF 151 MEG system. |
== Required background == These tutorial pages suppose you are comfortable with the basic concepts of MEG and EEG source imaging. If you're not, we engage you to read some background information, which will quickly help you getting up to speed with this field: |
