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).\n\nExcluded subjects: sub-019, sub-020, sub-021, sub-022, sub-026\n\nCohort demographics\n-------------------\n\nCohort 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).\n\nHow to cite\n-----------\n\nPlease cite the original SparrKULee data descriptor when using this dataset: Accou, B., Bollens, L., Gillis, M., Verheijen, W., Van hamme, H., & Francart, T. (2024). SparrKULee: A Speech-Evoked Auditory Response Repository from KU Leuven, Containing the EEG of 85 Participants. Data, 9(8), 94. https://doi.org/10.3390/data9080094\n\nWhere extra metadata lives (after NEMAR preparation)\n----------------------------------------------------\n\n  * `/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.\n  * `/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.\n  * `/code/convert_accou2023.py` — the exact script that was run to produce this NEMAR re-host.\n\n-------------------------------------------------------------\n\nREADME\n======\n\n__SparrKULee__: A Speech-evoked Auditory Response Repository of the KU Leuven, containing EEG of 85 participants\n\nOverview\n--------\n\nAn overview of the dataset including details about the filetypes, methods and technical validation can be found in [our\npaper]()\n\n\nNotes\n-----\n\nCode to download, preprocess and validate the data can be found at https://github.com/exporl/auditory-eeg-dataset.\n\nDue to mistakes during recording, following recordings do not have an adequate number of triggers and can therefore not be accurately aligned with the stimulus:\n\n1. sub-006/ses-shortstories01/eeg/sub-006_ses-shortstories01_task-listeningActive_run-06_eeg.bdf.gz\n2. sub-017/ses-shortstories01/eeg/sub-017_ses-shortstories01_task-listeningActive_run-03_eeg.bdf.gz\n3. sub-048/ses-varyingStories05/eeg/sub-048_ses-varyingStories05_task-listeningActive_run-04_eeg.bdf.gz","bids_version":"1.9.0","sessions_count":11,"publish_date":"2026-04-29 22:55:16","embedding_dirty":0,"license_tier":"noncommercial","zarr_status":"ready","zarr_converted_at":"2026-09-03 12:53:25","zarr_store_count":0,"zarr_index_etag":"a04bea620e131e59ed46fb8f546aed55","zarr_source_commit":"1276a3b7a056aaf8b619969b47e9e9782ec217c7","archive_status":null,"archive_size":null,"archive_retry_count":0,"records_status":null,"archive_skip_reason":"Archive (>100 GB) removed to save space; use the per-file direct download (#752).","zarr_errors":0,"zarr_failure_count":0,"zarr_deterministic":0,"zarr_failed_at":null,"num_dataset_citations":0,"num_datapaper_citations":0,"n_channels":null,"electrode_system":null,"has_hed":0,"hed_version":"8.2.0","is_exemplar":0,"bytes_present":null,"data_complete":null,"withdrawn_at":null,"withdrawn_reason":null,"archive_complete":null,"archive_absent_files":null,"archive_declared_files":null,"zarr_pool_breaks":0,"total_recording_duration":null,"recording_duration_min":null,"recording_duration_max":null,"recording_count":0,"recordings_unavailable":0,"recordings_measured":0,"channel_count_min":null,"channel_count_max":null,"sampling_frequency":null,"power_line_frequency":null,"eeg_reference":null,"placement_scheme":null,"sweep_stamps":"{\"enrichment_updated_at\":null,\"metadata_updated_at\":\"2026-05-16 07:35:25\",\"archive_checked_at\":\"2026-06-17 01:02:40\",\"zarr_checked_at\":\"2026-06-07 17:58:34\",\"records_checked_at\":null,\"citations_updated_at\":\"2026-08-17 03:01:00\",\"channel_montage_checked_at\":\"2026-06-28 22:59:53\",\"hed_checked_at\":\"2026-06-30 04:29:58\",\"data_checked_at\":null,\"availability_report_at\":\"2026-07-23 01:09:06\",\"signal_defaults_at\":\"2026-09-02 11:47:29\",\"recording_stats_at\":\"2026-09-04 03:00:20\"}","participants":85,"num_citations":0,"latest_version":"v1.0.0","zarr_verify_status":null,"zarr_verified_at":null,"owner_username":"bruaristimunha","owner_github":"bruAristimunha","file_size_formatted":"126 GB","zarr_data_failures":null,"zarr_index_url":"https://zarr.nemar.org/nm000238/zarr/index.json","attestation_deposit_type":null,"attestation_key_status":null,"attestation_deidentified":null,"attestation_no_duplicate":null,"attestation_upstream_source":null,"attestation_accepted_at":null}}
