HBCD EEG Utilities🔗

DOI

The HBCD EEG Utilities repository contains HBCD-EEG-Utilities.m, a MATLAB script that computes EEG derivatives from HBCD EEG .set files that have been processed with the HBCD-MADE pipeline.

This script is designed for users of HBCD EEG data who wish to use derivatives developed by the HBCD EEG Working Group. See Derivatives and ERP Specifications for a description of outputs.

HBCD_EEG_Utilities.m calls on a series of functions contained in HBCD-EEG-Utilities/supplemental files. Functionality of the software is as follows:

  • Load HBCD EEG .set files
  • Computes derivatives for each selected task
  • Saves trial-level and summary statistics output per participant for the VEP, MMN, and FACE tasks
  • Saves power spectrum output for the RS task
  • Writes subject-level summary statistics and trial measures output tables as .csv files
  • Concatenates all subjects' summary statistics output into a single spreadsheet for each task
  • Concatenates all subjects' trial measures output into a single spreadsheet for each task

Functionality🔗

The following MATLAB scripts and .json files in the HBCD-EEG-Utilities repository are required for processing. 

|__ HBCD-EEG-Utilities/
    |
    |__ HBCD_EEG_Utilities.m #load data, compute mean amplitude, generate output tables
    |
    |__ supplemental files/
        |
        |__compute_peaks_latencies.m #compute adaptive mean and latency measures for VEP
        |__concatenate_files_summary.m #combine all subjects' summary statistics into one .csv
        |__concatenate_trial_measures.m #combine all subjects' trial data into one .csv
        |__get_Cluster.m #define clusters used for ROIs
        |__grab_settings.m #read in processing settings from proc_settings_HBCD.json
        |__RS_ERP_Topo_Indv.m #calculates power values for RS and save output to .csv files
        |
        |__proc_settings_HBCD.json #specify processing settings
