ERPLAB Studio Manual

Version 11

ERPLAB Toolbox is an open-source Matlab package for analyzing event-related potentials (ERPs). The original version of ERPLAB, now called ERPLAB Classic, is a plugin that operates within the EEGLAB package. ERPLAB Studio is a standalone application that implements the same underlying ERPLAB and EEGLAB code from a more user-friendly GUI. This manual is for ERPLAB Studio; there is a separate manual for ERPLAB Classic and a detailed wiki for EEGLAB. Additional ERPLAB documentation is available on our GitHub Wiki page.

Many EEGLAB operations can be called from ERPLAB Studio. However, some of the more advanced EEGLAB operations are unavailable from ERPLAB Studio. If you want to use those operations, you can do some of your processing in EEGLAB and some in ERPLAB Studio. They use the same EEG data structures and file formats, so you can read EEGLAB files into ERPLAB Studio. You can also write scripts that access all the EEGLAB functions and all the ERPLAB functions.

If you are new to ERPLAB, please go through the ERPLAB Studio Tutorial before attempting to use our software. This will require some initial investment of time, but it will end up saving you time and frustration in the long run. If you have already used ERPLAB Classic but are new to ERPLAB Studio, you can instead read the brief ERPLAB Studio Transition Guide and ICA-Based Artifact Correction Tutorial. If you are new to ERP research, you can read An Introduction to the Event-Related Potential Technique to learn the general theory behind ERP research and Applied Event-Related Potential Data Analysis to learn how to apply that theory to real data.

If you run into problems using ERPLAB Studio, please see our Troubleshooting and Frequently Asked Questions page. If you have questions about using the software or comments of general interest, please post them to the ERPLAB email List. To report bugs, please send an email to erplab-bugreports@ucdavis.edu (including as much detail as possible so that we can reproduce the problem).
