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 v6.1.4

To install ERPLAB v6.1.4, download the zip file (linked above), unzip and place the folder in the 'plugins' folder of your existing EEGLAB installation (e.g. ~/Documents/MATLAB/eeglab13_6_4b/plugins/erplab6.1.4/). Additional 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.

  • We recommend a 64 bit OS, 64 bit Matlab, and at least 4 GB RAM. Most modern computers meet this.
  • The Matlab Signal Processing Toolbox is required
    • Entering in the command ver in the Command Window will produce a list of installed toolboxes. Check this list to see whether the Signal Processing Toolbox is installed
  • Caution: EEGLAB v11 is not recommended.

ERPLAB v6.1.4

Some additions and minor bugfixes, including:

  • Removing channels can now avoid deleting all channel location information
  • More channel location tools
  • Measurement Window GUI now fits on a smaller screen
  • Improvements in 'Preprocess Continuous EEG' options
  • Fixed a bug where the number of loaded erpsets would be mistakenly taken to be zero
  • Improved Current-Source-Density compatibility
  • Replaced the error 'Quack' noise with a beep, and replaced some error pictures.

ERPLAB v6.1.3

Minor bugfixes, including:

  • Cleaned up the Measurement Viewer text and options
  • Measurement Viewer helper text now only shown when relevant

ERPLAB v6.1.2

Minor bugfixes, including:

  • Fixed BDF Library url-link in BDF-Visualizer
  • Swapped artifact and user-flag display in BDF-Visualizer

ERPLAB v6.1.1

Minor bugfixes, including:

  • Shift Event Codes GUI fix - now doesn't crash on launch.
  • Adopted [Major].[Minor].[Patch] version numbers, this being v6.1.1, with backward-compatible file loading. Note - from v6.0, we no longer indicate the file type usage in the version number, and this is now always taken to be 1.

ERPLAB v6.1 Release Notes

Shift Event Codes

The new Shift Event Codes tool has been updated so that when you shift event codes beyond a continuous EEG boundary marker (e.g. -99, "boundary" event codes) then that code will be deleted

New Github-based documentation & ERPInfo.org website

We have fully migrated of all our ERPLAB documentation (i.e. manual, tutorial, etc) now to Github, and so have now updated the help links in ERPLAB.

ERPLAB v6.0 Release Notes

With ERPLAB v6.0, we include a variety of new features, user-interface improvements, bug-fixes, and improvements to existing functions. Among these, we have:

- Current Source Density Tool

EEG or ERP data can be used to compute an estimate of the Current Source Density (CSD). We include new functions to take data loaded in ERPLAB (either EEG or ERP) and compute the CSD data. We use CSD methods from Jürgen Kayser (from the CSD Toolbox).

These tools can be found in the new 'ERPLAB -> Data Transformations' menu. A new ERPLAB dataset is generated, with CSD data in the place of EEG/ERP data.

Find CSD documentation here

- Fractional peak measurement can now be offset (post-peak) as well as onset (pre-peak)

In the ERP Measurement tool, ERPLAB can record measurements of local peaks and the time of a fractional peak, like 50% peak. Previously, this fractional peak measurement was taken from the 'onset' of the peak, before the peak. In v6.0, ERPLAB also has an option to measure the fractional peak 'offset', the 50% peak value after the peak.

- ERPLAB documentation on GitHub

For more easy editing, ERPLAB documentation has been moved to a wiki here.

- Continuous EEG Preprocessing tools

- Delete Time Segments tool

With the new Delete Time Segments tool you can now remove segments of irrelevant continuous EEG data, like data recorded during breaks in the experiment.

- Time delay event code shifting tool

With the new Shift Event Codes tool you can now time-shift specific event codes either to either earlier or later timepoints in the EEG data. This tool was created to counter the delay between visual stimulus onset on the monitor and its corresponding event code recorded in the EEG data.

- Selective Electrode Interpolation tool

The new Selective Electrode Interpolation tool is based off of EEGLAB's own interpolation function and adds the ability to specify which electrodes to use as input for interpolation.
