Eighteenth EEGLAB Workshop

Rio de Janeiro, Brazil - September 7-10

The 18th EEGLAB Workshop was held from Sunday, September 7th through Wednesday, September 10th at the Neurology Institute Deolindo Couto of the Federal University of Rio de Janeiro. Participants were expected to bring laptops with Matlab installed so as to be able to participate in the practical sessions. The workshop introduced and demonstrated the use of EEGLAB and EEGLAB plug-in tools for performing analysis of EEG and related data, with detailed method expositions and practical exercises.

NOTE: The workshop will be fairly technical, some sessions requiring basic Matlab programming skills. Therefore this workshop might not be suited for people who are just beginning EEG research with quite limited knowledge of it. Rather, the intended attendees are those performing EEG research who want to learn to perform more flexible and in-depth analysis methods, or who are advanced experts and want to share their analysis methods with the world in the form of plug-in extensions to the EEGLAB environment.

Material for download

Material from the workshop will be available here

To access the talk slides, use the links in the Program listing below! Slides were made available during the workshop.

Download EEGLAB. Download the latest version of EEGLAB (needs updating!)

Download a sample EEG dataset. Download an example dataset used in the tutorial on independent component properties.

Download tutorial scripts Download Matlab scripts and data for the tutorial sessions on writing scripts dealing with independent component processes.

Download a single-subject EEGLAB dataset. This dataset will be used in the first few Tutorial sessions.

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 EEG studies.

Relevant reading material

EEGLAB graphic interface is built on top of the powerful Matlab scripting language. Enjoying the full capabilities of EEGLAB for building macro commands and performing custom and automated processing requires the ability to manipulate EEGLAB data structures in Matlab. Because of time constraints, we will NOT provide an introduction to the Matlab language. Instead users need to familiarize themselves with Matlab prior to the workshop.

Users of Matlab 7: We recommend running the following demos and reading the following help sections.

After opening the Matlab desktop, select menu item "Help Demos" and run the following demos. Note that while the 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. 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.
