In eegverse/erpcore: Download ERP CORE Data

erpcore

The goal of erpcore is to provide some simple command line functions for downloading the ERP CORE (Kappenman, Farrens, Zhang, Stewart, & Luck, 2021) datasets from the Open Science Framework website.

In their own words:

The ERP CORE is a freely available online resource consisting of optimized paradigms, experiment control scripts, example data from 40 participants, data processing pipelines and analysis scripts, and a broad set of results for 7 different ERP components obtained from 6 different ERP paradigms:

• N170 (Face Perception Paradigm)

• MMN (Passive Auditory Oddball Paradigm)

• N2pc (Simple Visual Search Paradigm)

• N400 (Word Pair Judgement Paradigm)

• P3b (Active Visual Oddball Paradigm)

• LRP and ERN (Flankers Paradigm)

For more information about the ERP CORE, visit their website.

You can also directly access the data at the Open Science Framework website

Installation

You can install the development version from GitHub with:

# install.packages("remotes")
remotes::install_github("eegverse/erpcore")

Usage

The get_erpcore() function can be used to download individual components from the ERP CORE datasets. For example, you can request to download the N170 data. By default, the data will create a new directory in your current working directory.

get_erpcore(component = "n170")

The data can be requested in three different formats:

get_erpcore(component = "n170", type = "raw")
get_erpcore(component = "n170", type = "bids")
get_erpcore(component = "n170", type = "all")

• "raw" returns the original data in .set format, along with processing scripts for the Matlab ERPLAB toolbox.
• "bids" returns the same data in a BIDS compliant organization.
• "all" returns the raw data, copies of fully-processed data, and copies of the data at every stage of preprocessing.

You can also use one of the specific functions for each component. For example, to request the data for the N400 component in BIDS format, you can use:

get_n400(type = "bids")
