Data Outputs Overview

Raw EEG and other output data are automatically stored by the software at:
where xxxx = Subject # , and y = Group #

Gathering the Data Output Files

EEG raw data will be automatically saved in two file formats: Extensible biosignal(*.ebs) and European Data Format (*.edf), with the latter as a compatible format with most third-party EDF-file viewers. Other data generated by the B-Alert software are listed below:

Toggle Summary Table

File Name Suffix Description
*.Decon.edf Decontaminated data from the Signals.Raw.edf file
*_Events.edf Compatible third party events data generated by the External Syncing Unit in EDF+ annotation.
*.Impedance.Results.csv A log containing the recorded impedances for each channel when performing Check Impedance
*.Ref_Raw.csv Absolute Power Spectral Density (1-40Hz), Relative PSD (1-40Hz), and EEG Frequency Bands
*.Ref_Class.csv Absolute Power Spectral Density (1-40Hz), Relative PSD (1-40Hz), and EEG Frequency Bands with Kaiser Windowing applied
*.HR_beat.csv Heart Rate Data, based on interbeat interval
*HR_epoch.csv Heart Rate Data, based on second-by-second interval
*.Classification.csv Output probabilities based on the ABM Cognitive State and Workload metrics
*.Diff_Raw.csv PSD Data and EEG Frequency Bands for differential channels
*.Diff_Class.csv PSD Data and EEG Frequency Bands for differential channels with Kaiser Windowing
*.ZScore.csv Z-Score values per epoch mean and SD, for the ABM Cognitive State and Workload metrics’ probabilities.
*ZScore_psd.csv Z-Score values for PSD on specified channels
*.thirdparty.bin Third-party packets sent to External Syncing Unit
*.Actigraphy.bin Raw output values from embedded headset accelerometer
*.Artifact.csv Detected artifacts at specified channels with start and end epoch markers, and predicted artifact type
