A 4-hour session, including lectures and a hands-on workshop on Brainstorm, will be featured as part of the [[https://micmac-workshop.org/|MicMac Conference in Toulouse, France]]. This scientific event focuses on intracranial electrophysiological recordings using micro- and macro-electrodes. The hands-on session will explore Brainstorm's features for sEEG analysis, allowing participants to learn how to use the software effectively. Attendees will also gain access to Brainstorm's new tools and practice using them on their personal laptops.

== Requirements ==
In order to make the workshop as efficient as possible, we ask all the attendees to: <<HTML(<FONT color=red>)>>''' download, install and test'''<<HTML(</FONT>)>> the software and <<HTML(<FONT color=red>)>>'''download'''<<HTML(</FONT>)>> the workshop dataset on their laptops prior to the workshop.

{{{#!wiki tip

We highly recommend bringing an '''external mouse''' on the workshop day. Most of the manipulations are done with the mouse, and some involve an intense use of the scrolling operation.
}}}
== Installing Brainstorm ==
Please read carefully the following instructions on: <<BR>>[[WorkshopGeneralInstall|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.

 1. The data is distributed as '''raw''' and '''pre-processed''' data.
  a. '''raw data''' is located in the file '''`WorkshopSEEG_raw.zip`''' which  contains raw SEEG recordings (in EDF format), T1 MRI, T2 FLAIR MRI, Diffusion Weighted MRI and CT scan (all in NIfTI-1 format). The raw SEEG recordings correspond to:
   i. Two files containing seizure onset:
    * Seizure onset with Low-voltage-fast-activity
    * Seizure with Ictal repetitive spiking
   i. One file with interictal spike, and
   i. One file containing baseline recordings

  a. '''pre-processed data''' is located in the file '''`WorkshopSEEG_precomputed.zip`''', which contains a Brainstorm protocol with the raw data already pre-processed.

 1. Once you have successfully installed and tested Brainstorm (see previous section), proceed to download the data to be used in the workshop.
  a. Download the '''raw data (512 MB)''':
   * [[https://neuroimage.usc.edu/resources/bst_workshop/Data/WorkshopSEEG_raw.zip|WorkshopSEEG_raw.zip]].<<BR>>Unzip the downloaded raw data on your desktop: it will create a new folder named '''`WorkshopSEEG_raw`'''

  a. Download the '''pre-processed data (3.5 GB)'''. Do not unzip this file:
   * [[https://neuroimage.usc.edu/resources/bst_workshop/Data/WorkshopSEEG_precomputed.zip|WorkshopSEEG_precomputed.zip]]

 1. 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)
  * '''`WorkshopSEEG_raw.zip`''': Raw data, for SEEG localization demonstration
  * '''`WorkshopSEEG_precomputed.zip`''': Pre-processed Brainstorm protocol for workshop session

We will provide [[https://neuroimage.usc.edu/resources/bst_workshop/2025_toulouse/Walkthrough-Workshop-Toulouse-2025.pdf|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)'''.

== Bring your own data ==
At the end of the session, the Brainstorm team will dedicate their time to address participants' requests. We encourage you to bring in your own sample of data that you would be interested in processing with Brainstorm.

The file formats that can be read by Brainstorm are listed on the [[http://neuroimage.usc.edu/brainstorm/Introduction#Supported_file_formats|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 )

== Brainstorm prerelease ==
We are also excited to offer early access to a version that's still in development, designed specifically for gathering your invaluable feedback on features and usability featuring Automatic SEEG contact localization and labeling.

{{{#!wiki important
This is a prerelease version, and while we’ve built it with care, it may not be completely stable. We're offering it solely to gain insights from real user experiences. Your participation will directly impact improvements and feature enhancements in the final release.
