The data has been organised according to the BIDS standard for more accessible reuse. Recordings are approximately 7 minutes long with eyes opened or closed, as indicated by task.\n\n## Usage\n\nFor loading and using the data in Matlab we recommend using pop_importbids by EEGLab, example usage here: https://eeglab.org/tutorials/11_Scripting/Analyzing_EEG_BIDS_data_in_EEGLAB.html\n\nFor a complete pipeline for resting state EEG preprocessing and feature extraction in Matlab we recommend DISCOVER-EEG:\nCristina Gil. (2024). crisglav/discover-eeg: 2.0.0 (2.0.0). Zenodo. https://doi.org/10.5281/zenodo.10797803\n\n## Phenotype data note\n\nSession-level questionnaire data are stored in `phenotype/pain-questionnaire_sessions.tsv` with descriptions of the corresponding questionnaire items in `phenotype/pain-questionnaire_sessions.json`. The phenotype files are currently ignored by the BIDS Validator due to incomplete support for phenotype indexing across multiple sessions.\n\n## License\nCC0","bids_version":"1.9.0","sessions_count":5,"publish_date":null,"embedding_dirty":0,"license_tier":"public","zarr_status":"ready","zarr_converted_at":"2026-08-23 20:08:01","zarr_store_count":152,"zarr_index_etag":"c38d11a2014e663f47ba485d33d74145","zarr_source_commit":"823b194ce575d75b59860bb07c4554b2d1f7094a","archive_status":"ready","archive_size":62440196618,"archive_retry_count":0,"records_status":"ready","archive_skip_reason":null,"zarr_errors":0,"zarr_failure_count":0,"zarr_deterministic":0,"zarr_failed_at":null,"num_dataset_citations":1,"num_datapaper_citations":0,"n_channels":63,"electrode_system":"10-10","has_hed":0,"hed_version":null,"is_exemplar":0,"bytes_present":69691994437,"data_complete":1,"withdrawn_at":null,"withdrawn_reason":null,"archive_complete":null,"archive_absent_files":null,"archive_declared_files":null,"zarr_pool_breaks":0,"total_recording_duration":61062.83999999994,"recording_duration_min":133.24,"recording_duration_max":660.02,"recording_count":152,"recordings_unavailable":0,"recordings_measured":152,"channel_count_min":64,"channel_count_max":128,"sampling_frequency":2400,"power_line_frequency":50,"eeg_reference":"Average, or channel A1 placed on left ear","placement_scheme":"International 10-10","sweep_stamps":"{\"enrichment_updated_at\":\"2026-08-19 00:14:10\",\"metadata_updated_at\":\"2026-08-19 00:14:22\",\"archive_checked_at\":\"2026-06-29 18:23:52\",\"zarr_checked_at\":null,\"records_checked_at\":\"2026-06-29 17:45:13\",\"citations_updated_at\":\"2026-09-08 03:00:53\",\"channel_montage_checked_at\":null,\"hed_checked_at\":\"2026-06-30 05:39:42\",\"data_checked_at\":\"2026-08-31 03:00:33\",\"availability_report_at\":\"2026-07-23 01:30:42\",\"recording_stats_at\":\"2026-09-02 11:33:49\",\"signal_defaults_at\":\"2026-09-02 12:50:16\"}","participants":38,"num_citations":1,"latest_version":"v1.0.0","zarr_verify_status":null,"zarr_verified_at":null,"owner_username":"nemarAdmin","owner_github":"nemarAdmin","file_size_formatted":"64.91 GB","zarr_data_failures":null,"zarr_index_url":"https://zarr.nemar.org/on006921/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}}
