Mumbai, India June 28-30, 2023
Practical workshop on EEG/MEG analysis at IIT Bombay.
Three-day Brainstorm training, EEG- and MEG-oriented.
During the first two days, participants will process an EEG/MEG dataset to learn and explore Brainstorm features. On the last day, participants are encouraged to bring their own data, which we will review in small groups.
General information
| Where | IIT Bombay |

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. Please note that this session will be run on workstations available at the IITB.
Installing Brainstorm
We will use pre-installed versions installed on IITB workstations. If you would like to use your own laptop, please read carefully the following instructions:
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 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 (see previous section), proceed to download the dataset for the workshop.
- Download the tutorial dataset (5 GB):
- Unzip the downloaded file on your desktop: it will create a new folder named ds000117-iitbombay.
- Final check: after following the steps above, you should have 3 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)

We provide a detailed step-by-step walkthrough of the data analyses performed during the training.
Bring your own data
The last session will be mostly dedicated to addressing participants' requests. We encourage you to bring in your own sample of EEG/MEG/ECoG/sEEG data that you would be interested in processing with Brainstorm. We may ask that you pair with other attendees, for logistics purposes.
The file formats that can be read by Brainstorm are listed on the Introduction page. Please contact us in advance if you are not sure your dataset can be imported in Brainstorm. If you do not have data available, you may continue to use the tutorial dataset used in the present workshop.
