# Nineteenth EEGLAB Workshop

Aspet, France - May 25-29, 2015

The 19th EEGLAB Workshop will take place from Monday, May 25th through Friday, May 29th in the village of Aspet in the Pyrenees foothills in southwest France near Toulouse. Participants will be expected to bring laptops with Matlab installed so as to be able to participate in the practical sessions. The tutorial workshop will introduce and demonstrate the use of the EEGLAB software environment and EEGLAB-linked tools for performing advanced analysis of EEG and related data, with detailed method expositions and practical exercises. The workshop will be held at a French family vacation camp, with hiking and other recreational opportunities available. Meals will be served family style.

## Registration and cost

To reimburse travel expenses of Workshop faculty and facilities rental, costs for the workshop will be as follows:

Registration cost is **570 Euros for students and post-docs in two-person rooms, ** and **790 Euros for faculty and others with private rooms** (Note: A discounted price is available if you come from a French laboratory since this workshop is sponsored by the CNRS). The registration costs includes shuttle bus transportation rfom the Toulouse airport to Aspet (about 1 hour) and back, conference space rental, all coffee breaks, and a short excursion by bus to the Pyrenees mountains. In addition, **the total cost of room and board for 5 days, 4 nights lodging with all meals is included**. Note that this is a non-profit event for which the faculty are not compensated.

The facility where the workshop will take place is the Bois Perche, a family-oriented rural facility. We have held four enjoyable EEGLAB workshops at this location since 2007.

Space at the workshop is limited to 40 participants and is available on a first come, first served basis.

**Warning: ** This workshop is not for beginners in EEG and Matlab - such persons would be wasting much of their time. Some parts of the workshop are fairly technical. The main topics will be advanced methods for analyzing EEG and allied behavioral data, methods including spectral decomposition, independent component analysis, inverse source analysis, information flow, etc.. Some other parts of the workshop will require basic Matlab scripting capabilities. If you are interested in a slightly more basic EEGLAB workshop, you might want to attend the one in Sheffield in September 2015 (though this workshop will not be aimed at true EEG beginners either). Some basic web resources for learning Matlab are discussed below.

## Downloads

**To access most recent previous versions the talk slides and videos, use the links in the Program listing below! Slides will be made available during the workshop.**

Download EEGLAB. Download the latest version of EEGLAB 12.0.2.1b.

Optional download below. Data will be made available on USB keys during the workshop.

Download a smaller version of the same EEGLAB dataset. This is the same dataset as above but is cut down in size for people who encounter out-of-memory issues in working with the full dataset.

Download an EEGLAB STUDY with data from 13 subjects. This is a VERY large (2.3GB) file and may even fail to download the first few times you try. Make sure you have a fast and reliable Internet connection before attempting this download.

Download an EEGLAB STUDY with 5 subjects (1.8 GB). Optional download for more exploration of EEGLAB studies.

The following files are needed for the Source Information Flow Toolbox (SIFT) practicum:

Please visit the SIFT website to download all the available files (SIFT Toolbox, ARFIT toolbox, and Sample Data (143 Mb). We also highly recommend that you download the SIFT Handbook/Manual as we will use this for exercises.

## Relevant reading material

The EEGLAB graphic interface is built using the powerful Matlab scripting language. Enjoying the full capabilities of EEGLAB for building macro commands and performing custom and automated processing requires basic knowledge of how to manipulate EEGLAB data structures in Matlab. Because of time constraints, we will NOT provide an introduction to Matlab scripting. Instead, attendees must familiarize themselves with Matlab **before** coming to the workshop.

New users of Matlab: We recommend running the following demos and reading these help sections:

After opening the Matlab desktop, select menu item "Help Demos" and run the following demos. Note that while a demo is running, you can retype the text (or copy it) to the main Matlab window:

- Mathematics - Basic Matrix Operations
- Mathematics - Matrix manipulations
- Graphics - 2-D Plots
- Programming - Manipulating Multidimentional arrays
- Programming - Structures

In the Help Content, read and practice at least the following sections:

- Getting Started - Matrices and Arrays - Matrices and Magic squares
- Getting Started - Matrices and Arrays - Expressions
- Getting Started - Matrices and Arrays - Working with Matrices
- Getting Started - Graphics - Basic plotting functions
- Getting Started - Programming - Flow Control
- Getting Started - Programming - Other data structures
- Getting Started - Programming - Scripts and Functions

Each section or demo (if read thoroughly) should take you about 10 minutes, for a total here of about 2 hours. If you do not use Matlab regularly, we encourage you to watch these demos, read these sections, and practice using the skills they introduce over several days.

If you do not have access to the Matlab demos, here is a short online introduction to Matlab (recommended pages, 1 to 12)

*IMPORTANT NOTE:* A portion of the workshop will be dedicated to writing EEGLAB scripts -- Not being able to understand Matlab syntax will mean you will miss out on a large portion of the workshop.

*EEGLAB WIKI:* Refer to the EEGLAB tutorial wiki for additional help.
