ERPLAB Toolbox Tutorial

ERPLAB TOOLBOX TUTORIAL

Important note: In some cases, errors will lead to a message that instructs you to report the error to the EEGLAB developers.  If this happens, please report the error to us at erplab@erpinfo.org and not to the EEGLAB developers.

ERPLAB has primarily been tested using EEG collected with a Biosemi ActiveTwo System, along with a smaller amount of testing using EEG collected with Neuroscan and EGI systems. Consequently, you should be particularly careful when using this version of ERPLAB with data collected with systems other than the Biosemi ActiveTwo.

ERPLAB Toolbox is in a period of rapid development. Some features are present in this version that have not yet been documented, and some features may have changed since this document was released. In addition, some of the screen shots shown in this document may reflect previous versions and may not conform with the text.  The documentation, like the software, is a work in progress.

The goal of this tutorial is to provide step-by-step instructions for the processing of a typical data set.  For an overview of ERPLAB Toolbox and detailed information about each specific function, see the ERPLAB User's Manual. A Frequently Asked Questions document is also available.  All documentation is available at http://erpinfo.org/erplab/erplab-documentation.

We have set up three web-based discussion groups.  One is designed for people to ask questions and give and receive advice about how to use ERPLAB Toolbox.  Another is designed for reporting bugs and describing work-arounds.  The third is designed to give users the opportunity to make suggestions about modifications and new features.  They can be accessed at http://erpinfo.org/erplab/erplab-discussion/erplab-discussion-forum/ (you will need to join the erpinfo.org web site to access these discussion groups).  There is also an email list, erplab@erpinfo.org, that you can use to send questions and announcements to the community of ERPLAB users.  If you would like to join this list, you should go to http://mail01.cmb.ucdavis.edu/mailman/listinfo/erplab.  To communicate privately with the developers, send an email to erplabtoolbox@gmail.com.

Please keep in mind that this is FREE software, and we do not have the resources to provide the level of support that commercial software vendors can provide.
