Installation

ERPLAB is a toolbox plugin for analyzing event-related potential data. It works within the EEGLAB Matlab environment.

Requirements

• Matlab installed
• EEGLAB folder within Matlab folder path (download EEGLAB here)

There are two ways to install ERPLAB.

1. Use the EEGLAB Plugin Manager
2. Manually place the ERPLAB folder in EEGLAB/plugins

Install Method 1 - EEGLAB Plugin Manager (Matlab R2018a and after)

From EEGLAB v2019.0, the EEGLAB Plugin Manager includes ERPLAB.

First, run Matlab, and confirm that EEGLAB is in the Matlab path. The command which eeglab will reveal the current path to EEGLAB. If this path is empty, run addpath('C:\your_eeglab_path_here')

Start EEGLAB by running the eeglab command at the Matlab Command Window.

In the new EEGLAB window, hit File > Manage EEGLAB extensions.

In the EEGLAB Plugin Manger, select ERPLAB and hit install/update

Install Method 2 - Manually place the ERPLAB folder in EEGLAB/plugins

First, run Matlab, and confirm that EEGLAB is in the Matlab path. The command which eeglab will reveal the current path to EEGLAB. If this path is empty, run addpath('C:\your_eeglab_path_here')

In your file manager, navigate to that EEGLAB path.

Unzip the ERPLAB folder (download here) to the /eeglab/plugins folder.

Ensure that the path is formatted correctly, such that something like C:\your_path_here\EEGLAB\plugins\erplabX.X\eegplugin_erplab.m exists.

Confirm ERPLAB is installed correctly

Start EEGLAB by running the eeglab command at the Matlab Command Window.

On running EEGLAB, you should see confirmation that ERPLAB is installed in the Matlab Command Window: EEGLAB: adding "ERPLAB" v7.0 (see >> help eegplugin_erplab)

In the new EEGLAB window, you should see a menu entry for ERPLAB.
