Aix-en-Provence, France: October 4, 2021

Half-day workshop, as part of the CuttingEEG conference. This session will introduce new features for SEEG analysis. Participants will learn how to access these new tools from the Brainstorm environment on their personal laptops.

General information

Where	Cube classrooms
When	Monday October 4th, 2021: 8:30-12:15
Instructor	Francois Tadel
Audience	Users interested in analyzing sEEG/EEG/ECoG/MEG recordings using Brainstorm. Teaching in English.
Documents	Introduction slides | Tutorial walkthrough

Program (TBA)

This session is based on a simplified version of the SEEG/Epileptogenicity tutorial.

8:30-9:15	Onsite assistance in installing the material for the training session
9:15-9:45	Lecture: Brainstorm overview Software structure, typical data workflow Presentation of the example dataset (BIDS-iEEG)
9:45-10:45	Anatomy Database explorer MRI volumes, surfaces Anatomical parcellations Coregistration of pre- and post-implantation images
10:45-11:45	SEEG recordings Reviewing continuous SEEG recordings Montages and management of event markers Marking SEEG contacts on post-implantation image Anatomical labelling of SEEG contacts
11:45-12:15	Advanced topics - Based on participants' requests Time-frequency analysis: Identification of ictal HFO frequency bands Epileptogenicity maps: Localization of the seizure onset zone and propagation pathways FEM demo: MRI segmentation, tissue anisotropy with DTI, FEM forward modeling Open discussion with Bainstorm users

Prepare your laptop for the workshop

Important notes

• Working with MEG/EEG/SEEG recordings involves a lot of computational resources and large display windows. Therefore we recommend that you bring a laptop with a decent processing capacity, 4Gb RAM, a 64bit operating system, and a screen larger than 13".

• You would add to your comfort by bringing an external mouse. Most of the manipulations are done with the mouse, and some involve an intensive use of the mouse wheel/scrolling.

• Don't forget your power adapter!

Installation instructions

Before coming to the workshop, you need to download the software and the tutorial dataset from the Brainstorm website (200Mb). To streamline troubleshooting during the session, please save all the downloaded files on your Desktop.

1. Go to the Download page, complete the quick and free registration process.

2. If you don't receive the confirmation email, please check your spam folder.

3. Download the following files to your Desktop folder:

   • Brainstorm software: brainstorm_YYMMDD.zip (source+binary, 90 Mb)

   • Tutorial dataset: workshop_cuttingeeg.zip (162 Mb)

4. If you already have Brainstorm on your laptop, make sure to update it before coming.
5. Unzip the two downloaded files on your desktop, then delete them

6. Create a folder "brainstorm_db" on your Desktop

7. Final check: you should have now 3 folders on your desktop:

   • brainstorm3: Program folder, with the source code and the compiled executable

   • brainstorm_db: Brainstorm database (empty)

   • workshop_cuttingeeg: Example dataset used during the training session

8. Run Brainstorm, make sure it works correctly on your computer (see next sections)

Running Brainstorm for the first time

If you don't have a Matlab license, you can get a temporary one for the duration of the conference: https://cuttingeeg2021.lpl-aix.fr/t/matlab-installation-licenses-available/151

With Matlab (2014b minimum)

1. Start Matlab

2. Do NOT add brainstorm3 folder to your Matlab path: this will be done automatically

3. Go to the brainstorm3 folder
4. Type "brainstorm" in the command window
5. When asked for the database folder, pick the "brainstorm_db" you have just created

6. Install SPM12: Menu Plugins > spm12 > Install.

Without Matlab

1. Install the Matlab Runtime R2020a (9.8): Mathworks website

2. Run the program in brainstorm3/bin/R2020a/

   • Windows: Double-click on brainstorm3.bat

   • MacOS: Double-click on brainstorm3.command and wait for instructions

   • Linux: From a terminal, run:
     cd brainstorm3/bin/R2020a/
     ./brainstorm3.command

3. For troubleshooting, see the Installation page.

Make sure it works

To make sure Brainstorm works properly or your computer:

• Select the menu: Help > Workshop preparation.

• Follow the instructions: when you see the 3D figure, make sure you see both a transparent head surface and a brain surface. Try to rotate the view with your mouse, and zoom in and out with the mouse wheel or two-finger pad scroll.
