Trois-Rivières, Québec, Canada May 7-8, 2024

Practical workshop on EEG/MEG analysis at UQTR

Two-day Brainstorm training, EEG-oriented.
During the two days, participants will process an EEG dataset to learn and explore Brainstorm features. In the second day, participants are encouraged to bring their own data, which we will review in small groups.

Requirements

In order to make the workshop as efficient as possible, we ask all the attendees to: download, install and test the software and download the workshop dataset on their laptops prior to the workshop.

Installing Brainstorm

Please read carefully the following instructions on:
preparing your laptop for the training

Workshop dataset

The workshop dataset is based on the Frontiers Research Topic From raw MEG/EEG to publication: a collection of articles reporting the analysis of the same multimodal dataset using different software environments. During this workshop, we will go through the main processing steps using data from of the participants, following a similar processing pipeline as the one described in the article MEG/EEG Group Analysis With Brainstorm and the corresponding online tutorial.

Once you have successfully installed and tested Brainstorm (see previous section), proceed to download the dataset for the workshop.

1. Download the tutorial dataset: ds000117_S1R1.zip (820 MB):
   Download link

2. Unzip the downloaded file on your desktop: it will create a new folder named ds000117_S1R1. It contains raw data for one participant, one run.

3. Download the tutorial dataset: UQTR_S1S2_R1R2.zip (950 MB):
   Download link

4. Unzip the downloaded file on your desktop: it will create a new folder named UQTR_S1S2_R1R2. It contains pre-processed data for two participants, two runs each.

5. Final check: after following the steps above, you should have 4 folders on your desktop:

   • brainstorm3: the software folder, containing the source code and the compiled executable

   • brainstorm_db: your Brainstorm database (which should be empty for now)

   • ds000117_S1R1: Dataset 1 used during the workshop session

   • UQTR_S1S2_R1R2: Dataset 2 used during the workshop session

We provide a detailed step-by-step walkthrough of the data analyses performed during the training.

Bring your own data

If time allows, the last part of the second day will be dedicated to addressing participants' requests. We encourage you to bring in your own sample of EEG iEEG data that you would be interested in processing with Brainstorm. The file formats that can be read by Brainstorm are listed on the Introduction page.

Troubleshooting

For any technical problem, please contact Raymundo Cassani ( raymundo.cassani@mcgill.ca )
