Los Angeles, CA, USA: December 5th, 2024

Register Now: seats are very limited!

This full-day workshop will take place at the University of Southern California on Dec 5th, immediately prior to the American Epilepsy Society Meeting (AES 2024). This session will highlight Brainstorm's unique features for multimodal scalp electrophysiology data analysis (EEG/MEG), with a second focus on intracranial recordings (iEEG).

Participants are invited to their personal laptops for a unique hands-on experience (data will be provided).

Registration is now open via this page.

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 multimocal data. In the morning session we will work on combined EEG/MEG data sets. In the afternoon we will use SEEG dataset recorded at the Epilepsy Monitoring Unit at UTHealth Houston.

[The detailed data and program will be released asap]

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

1. raw data is located in the file WorkshopXXX_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 WorkshopXXX_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:

   • TBD

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

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

   • TBD
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)

   • workshopXXX_raw: Raw data, for SEEG localization demonstration

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