Compute on this dataset

Two routes today, with a third (in-browser one-click submission) landing soon.

  1. NeuroScience Gateway (NSG) portal.

    NSG runs EEGLAB / Brainstorm / MNE pipelines on supercomputing time donated by SDSC. Create an account, point a job at this dataset's S3 prefix (s3://nemar/nm000238), and submit.
    nsgportal.org →

  2. Local processing with nemar-cli.

    Pull the dataset to your machine and run any toolbox locally. Honors the published version pinning. 

    npm install -g nemar-cli
nemar dataset clone nm000238
cd nm000238 && nemar dataset get
  3. Just the files.

    rclone, aria2c, or any HTTPS client works against data.nemar.org/nm000238/ — the manifest carries presigned S3 URLs.

Direct compute access is coming soon. One-click NSG submission from this page is scoped for a follow-up phase. Tracked on nemarOrg/website#6.

============================================================= IMPORTANT — RESTRICTED SUBJECTS EXCLUDED FROM NEMAR RE-HOST =============================================================

IMPORTANT — 5 of the 85 original subjects (sub-019, sub-020, sub-021, sub-022, sub-026) are EXCLUDED from this NEMAR re-host because their raw EEG files are access-restricted on the KU Leuven Dataverse (HTTP 403 on download without a data-use agreement). Researchers who need these subjects should email sparrkulee@kuleuven.be to request access and download the data directly from https://rdr.kuleuven.be/dataset.xhtml?persistentId=doi:10.48804/K3VSND (DOI 10.48804/K3VSND). The re-host therefore contains 80 of the original 85 subjects, covering all 11 session types (shortstories01, varyingStories01..10).

Excluded subjects: sub-019, sub-020, sub-021, sub-022, sub-026

Cohort demographics

Cohort demographics (from Accou et al., Data 2024, 9, 94, Section 2.1): 85 original participants, 74 female / 11 male, aged 21.4 ± 1.9 years (mean ± SD), inclusion window 18-30 years, all normal-hearing (≤30 dB HL, 125-8000 Hz), native Dutch/Flemish speakers. Per-subject numeric ages are not published by the SparrKULee authors for privacy reasons; participants.tsv only ships 3-year binned ages in the age_range column (see participants.json for details).

How to cite

Please cite the original SparrKULee data descriptor when using this dataset: Accou, B., Bollens, L., Gillis, M., Verheijen, W., Van hamme, H., & Francart, T. (2024).

Where extra metadata lives (after NEMAR preparation)

  • /code/task-listeningActive_eeg.json — full recording-level EEG metadata (SamplingFrequency, Manufacturer, EEGChannelCount, EEGReference, PowerLineFrequency, ...). Relocated from the dataset root because the validator does not match the orphan top-level sidecar against the .bdf.gz data files.
  • /code/remarks/ — per-session free-form recording notes (.txt and .docx) originally placed under sub-XX/ses-YY/remarks/. Relocated so the validator does not see an arbitrary remarks/ folder inside BIDS session directories.
  • /code/convert_accou2023.py — the exact script that was run to produce this NEMAR re-host.

Overview

An overview of the dataset including details about the filetypes, methods and technical validation can be found in [our paper]()

Notes

Code to download, preprocess and validate the data can be found at https://github.com/exporl/auditory-eeg-dataset.

Due to mistakes during recording, following recordings do not have an adequate number of triggers and can therefore not be accurately aligned with the stimulus:

  2. sub-017/ses-shortstories01/eeg/sub-017ses-shortstories01task-listeningActiverun-03eeg.bdf.gz
