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
You can install the development version from GitHub with:
# install.packages("remotes")
remotes::install_github("eegverse/erpcore")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.setformat, 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")These resources are shared under the terms of a Creative Commons license (CC BY-SA 4.0).
