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.
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:
- Two files containing seizure onset:
- Seizure onset with Low-voltage-fast-activity
- Seizure with Ictal repetitive spiking
- One file with interictal spike, and
- One file containing baseline recordings
- Two files containing seizure onset:
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.
Download the raw data:
- TBD
Unzip the downloaded raw data on your desktop: it will create a new folder named workshopUTAH_raw
Download the pre-processed data. Do not unzip this file:
- TBD
- 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
