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 constrains, 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 and read these sections 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 large portion of the workshop will be dedicated to writing EEGLAB scripts, so not being able to understand Matlab syntax will result in you missing out on a large portion of the workshop.
Below are some seminal and important papers describing EEGLAB processing:
