Breckenridge, Colorado, USA: March 3rd, 2025

BreckenridgeConference

Full-day of lectures and a workshop on Brainstorm as part of the International Conference on Artificial Intelligence in Epilepsy and Neurological Disorders in Breckenridge. This session will be hands-on Brainstorm features for sEEG analysis.

Participants will learn how to use Brainstorm and access its new tools on their personal laptops.

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

In this workshop, we will be working on a SEEG dataset recorded at the Epilepsy Monitoring Unit at UTHealth Houston.

The data is distributed as raw and pre-processed data.

  1. raw data is located in the file WorkshopColorado_raw.zip which contains raw SEEG recordings (in EDF format), T1 MRI and CT scan (both in NIfTI format). The raw SEEG recordings correspond to:

    1. Two files containing seizure onset:
      1. Seizure onset with Low-voltage-fast-activity
      2. Seizure with Ictal repetitive spiking
    2. One file with interictal spike, and
    3. One file containing baseline recordings
  2. pre-processed data is located in the file workshopColorado_precomputed.zip, which contains a Brainstorm protocol with the raw data already pre-processed.

Once you have successfully installed and tested Brainstorm (see previous section), proceed to download the data to be used in the workshop.

  1. Download the raw data:

  2. Unzip the downloaded raw data on your desktop: it will create a new folder named workshopColorado_raw

  3. Download the pre-processed data. Do not unzip this file:

  4. 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)

    • workshopColorado_raw.zip: Raw data, for SEEG localization demonstration

    • workshopColorado_precomputed.zip: Pre-processed Brainstorm protocol for workshop session

We will provide a detailed step-by-step walkthrough of the data analyses performed at the training. In addition, results obtained in this workshop can be replicated with this script (to be updated).

End of the workshop, the main conference begins at 6 pm

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 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.

Troubleshooting

For any technical problem, please contact Takfarinas Medani ( medani@usc.edu ) & Chinmay ... Todo
