Twentieth EEGLAB Workshop

Sheffield, UK - September 2-5, 2015

EEGLAB is an open-source software environment for electrophysiological signal processing now widely used around the world, with a growing number of extensions available from many research groups. The 20th EEGLAB Workshop will be held from Wednesday, September 2nd until Saturday, September 5th 2015 at the University of Sheffield, UK. The workshop will consist of tutorials, demonstrations and practical sessions. It will be led by Scott Makeig, Arnaud Delorme, and John Iversen of the Swartz Center for Computational Neuroscience, UCSD. The residential course will be limited to 50 delegates; it promises to be a great opportunity to learn more about advanced EEG analysis and meet other EEG researchers from the UK and elsewhere. There will also be a poster session that will provide delegates with the opportunity to present some of their recent EEG work and to receive feedback from their colleagues. Registrants will be contacted by the workshop organiser with further details of the poster session.

Participants are expected to bring laptops with Matlab installed so as to be able to participate in the practical sessions. The workshop will introduce and demonstrate the use of EEGLAB and EEGLAB extension tools for performing analysis of EEG and related data, with detailed method expositions and practical exercises. There will be an opportunity for delegates to present some of their EEG work during a poster session.

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, nor for those arriving with no experience at all with Matlab. Rather, the intended attendees are those performing EEG research who want to learn to perform more flexible and in-depth analysis methods using EEGLAB.

The EEGLAB workshop will be preceded, on Tuesday 1st September, by a one-day EEG / LFP conference entitled, "Understanding neural excitation/inhibition: implications for typical brain function and clinical disorders." This is a free conference, but if you wish to attend you must register to attend separately. More information about this conference is provided here.

The workshop venue is approximately 20 minutes, by taxi, from Sheffield train station. If travelling from overseas, Manchester airport is probably the most convenient airport to fly into. There is a direct train from Manchester airport to Sheffield (~ 1 hour). The train journey from London to Sheffield is between 2 and 3 hours, and trains to Sheffield leave from St Pancras station.

If you have questions, please contact the local organiser Dr Elizabeth Milne

Material for download

Downloads below are optional. You will receive instructions by email regarding material for the workshop.

Material from past workshops are available here

To access previous versions of the talk slides, use the links in the Program listing below! New pdf files will be made available during the workshop.

First, download the latest version of EEGLAB.

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 some of the workshop.

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