Mumbai, India June 28-30, 2023
Practical workshop on EEG/MEG analysis at IIT Bombay.
Three-day Brainstorm training, EEG- and MEG-oriented.
During two days participants will process an EEG/MEG provided dataset to explore Brainstorm and its features. On the last day, participants are encouraged to explore their own data with Brainstorm.

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.
If you encounter any trouble at setting Brainstorm please show up 30 min before the start of 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 processing the same multimodal dataset using different software environments. We will process together one subject of this dataset, following the processing pipeline described in the article MEG/EEG Group Analysis With Brainstorm and the corresponding online tutorial.
Once you have successfully installed and tested Brainstorm (previous section), proceed to download the dataset for the workshop.
- Download the tutorial dataset (5 GB):
- Unzip the downloaded file on your desktop
- Final check: you should have 3 folders on your desktop:
brainstorm3: Program folder, with the source code and the compiled executable
brainstorm_db: Brainstorm database (empty)

- Bring your own data or prepare your questions
Bring your own data
The last session will be mostly dedicated to addressing participants' requests. We encourage you to prepare some EEG/MEG/ECoG/sEEG data you would be interested in processing with Brainstorm. If you are coming with colleagues, try to organize small groups with similar interests (1-4 people).
The list of file formats that can be read by Brainstorm is available on the Introduction page. Please contact us in advance if you are not sure your dataset can be imported in Brainstorm.
NOTE ON, IF THERE IS NOT DATA ON YOUR OWN, YOU CAN TRY WITH DATA AVAILABLE AT BRAINSTORM.
