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: iEEG-BIDS specification, MRI segmentation with CAT12, MRI/CT coregistration and non-linear MNI normalization with SPM12, management of anatomical atlases, interactive marking of SEEG electrodes, automatic SEEG contact labelling based on volume and surface parcellations, epileptogenicity mapping, advanced FEM modeling including DTI-based constraints with DUNEuro. Participants will learn how to access these new tools from the Brainstorm environment on their personal laptops.
General information

Program
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 |
| 9:45-10:30 | Anatomy Database explorer MRI volumes, surfaces Coregistration of pre- and post-implantation images |
| 10:30-11:30 | SEEG recordings Reviewing continuous SEEG recordings Montages and management of event markers Marking SEEG contacts on post-implantation image Projecting SEEG recordings on MRI and cortex surface |
| 11:30-12:15 | Epileptogenicity maps Importing epochs of interest in the database Time-frequency analysis: Identification of ictal HFO frequency bands Computation of epileptogenicity maps: Localization of the seizure onset zone Estimation of the propagation pathways |
Prepare your laptop for the workshop
Setting up the software environment is an important part of the training and is a good preparation step to this workshop. Follow the instructions below if you are insterested in following the hands-on session on your own laptop.
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.
Go to the Download page, complete the quick and free registration process.
If you don't receive the confirmation email, please check your spam folder.
Download the following files to your Desktop folder:
Brainstorm software: brainstorm_YYMMDD.zip (source+binary, 90 Mb)
Tutorial dataset: workshop_cuttingeeg.zip (162 Mb)
- If you already have Brainstorm on your laptop, make sure to update it before coming.
- Unzip the two downloaded files on your desktop, then delete them
Create a folder "brainstorm_db" on your Desktop
- 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
- Run Brainstorm, make sure it works correctly on your computer (see next sections)
Running Brainstorm for the first time
With Matlab (2014b minimum)
- Start Matlab
Do NOT add brainstorm3 folder to your Matlab path: this will be done automatically
- Go to the brainstorm3 folder
- Type "brainstorm" in the command window
- When asked for the database folder, pick the "brainstorm_db" you have just created
Install SPM12: Menu Plugins > spm12 > Install.
Without Matlab
Install the Matlab Runtime R2020a (9.8): Mathworks website
- 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 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.
