ERPLAB Toolbox is a free, open-source Matlab package for analyzing ERP data. It is tightly integrated with EEGLAB Toolbox, extending EEGLAB’s capabilities to provide robust, industrial-strength tools for ERP processing, visualization, and analysis. A graphical user interface makes it easy for beginners to learn, and Matlab scripting provides enormous power for intermediate and advanced users.

ERPLAB v9.00


To install ERPLAB v9.00, download the zip file (linked above), unzip and place the folder in the 'plugins' folder of your existing EEGLAB installation (e.g. /Users/Steve/Documents/MATLAB/eeglab2019_1/plugins/erplab/). More installation help can be found here.

To run ERPLAB, ensure that the correct EEGLAB folder is in your current Matlab path, and run eeglab as a command from the Matlab Command Window. Find our tutorial here.

We encourage most users to use this latest major version.


ERPLAB compatibility

We anticipate that ERPLAB will work with most recent OSs, Matlab versions and EEGLAB versions.

Release Notes

ERPLAB v9.00 Release Notes

Note: ERPLAB v9.00 is the recommended version for use with best practices in ERP data processing and analyses as outlined in Dr. Steven J Luck's new Applied Event-Related Potential Data Analysis e-book here.

Now includes: Ability to low-pass filter prior to marking EEG segments with all artifact detection routines (data is not saved with the filter).

Ability to calculate Data Quality measures (e.g. analytic SME) on multiple binned and epoched EEGset files prior to creating ERPs. -More information about the SME can be found here. -See Applied Event-Related Potential Data Analysis e-book here for best-practices on this approach.

Various fixes to the GUI layouts for many routines (e.g. "Delete Time Segments" for EEG processing).

ERPLAB v8.30 Release Notes

Now includes:

The ability to operate multiple Data Quality windows (See "Data Quality" introduced in v8.20).

Data quality windows have newly added features (e.g. outliers in each channel and time window).

Updated "Delete Time Segments" pre-processing tool to include the option to ignore boundary events.

Post-Artifact Detection Epoch Interpolation feature. See here.

Standard Measurement Error (SME) bootstrapping functions updated for use in custom scripts. -More information about the SME can be found here .

Various bug fixes with ERP plotting and measurements.

ERPLAB v8.02 Release Notes

ERPLAB v8.02 adds a colormap to help visualize the Data Quality Table info

ERPLAB v8.01 Release Notes

ERPLAB v8.01 adds binorgEEG functions to v8.0

ERPLAB v8.0 Release Notes

With ERPLAB v8.0, we include new tools for assessing measures of Data Quality Metrics in EEG ERP data.

  • Data Quality Metrics
    • The ERP Averager will calculate these Data Quality Metrics by default
    • A new submenu in the ERPLAB menu ('Data Quality options') allows access from the EEGLAB-ERPLAB GUI.
    • A new table interface to show all the data quality information from an ERP set with DQ_Table_GUI(ERP) or through the above GUI menu option.
    • These data quality metrics can be summarized on the Command Window, saved to Mat structure or exported to Excel, or plotted in the above interactive table.
    • The data quality information and metadata is stored in a new structure, ERP.dataquality

  • New options for calculating, viewing, and saving, frequency spectra, in the compute_fourier(EEG) function
