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## Usage\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\nFor a complete pipeline for resting state EEG preprocessing and feature extraction in Matlab we recommend DISCOVER-EEG:\nCristina Gil.

Zenodo. https://doi.org/10.5281/zenodo.10797803\n## Phenotype data note\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## License\nCC0","recording_modality":["eeg"],"senior_author":"Lendaro, E.","sessions":["1","2","3","4","5"],"size_bytes":69166826012,"source":"openneuro","study_design":null,"study_domain":null,"tasks":["EYESCLOSED","EYESOPEN"],"timestamps":{"digested_at":"2026-04-22T12:29:50.621241+00:00","dataset_created_at":"2025-11-10T11:05:50.395Z","dataset_modified_at":"2026-01-21T08:02:22.000Z"},"total_files":152,"storage":{"backend":"s3","base":"s3://openneuro.org/ds006921","raw_key":"dataset_description.json","dep_keys":["CHANGES","README.md","participants.json","participants.tsv"]},"tagger_meta":{"config_hash":"4a051be509a0e3d0","metadata_hash":"0fbd6e38501ac0c8","model":"openai/gpt-5.2","tagged_at":"2026-01-20T19:14:25.473839+00:00"},"tags":{"pathology":["Other"],"modality":["Resting State"],"type":["Clinical/Intervention"],"confidence":{"pathology":0.8,"modality":0.85,"type":0.7},"reasoning":{"few_shot_analysis":"Most similar few-shot example by paradigm is the dementia dataset (\"A dataset of EEG recordings from: Alzheimer's disease...\") which is resting-state EEG in a recruited clinical population and is labeled Modality=Resting State and Type=Clinical/Intervention. This guides treating a resting-state recording as Clinical/Intervention when the primary focus is distinguishing/characterizing a clinical condition. A contrasting example is the sleep deprivation resting-state dataset labeled Type=Resting-state because it is a manipulation in otherwise healthy participants.

ALIGN.\nModality: Metadata says \"resting state\" and describes \"eyes opened or closed\" recordings; few-shot conventions label such paradigms as Modality=\"Resting State\". ALIGN.\nType: Metadata explicitly indicates a resting-state paradigm but does not explicitly state an intervention; few-shot conventions show that when a clinical condition is the main grouping variable in resting-state EEG (e.g., dementia), Type is labeled \"Clinical/Intervention\" rather than \"Resting-state\". Mostly ALIGN (clinical-cohort emphasis), but there is mild ambiguity because it is also a pure resting-state recording.","decision_summary":"Pathology top-2: (A) Other — supported by \"amputees with phantom limb pain\" / \"amputees without phantom limb pain\" (condition not in allowed specific list) and matches few-shot convention for non-listed clinical groups; (B) Healthy — supported only by presence of \"intact, pain free controls\" but this is not the recruited condition of interest. Winner: Other.\nModality top-2: (A) Resting State — supported by \"resting state\" and \"eyes opened or closed\"; (B) Unknown — would apply if no task/paradigm described, but it is described. Winner: Resting State.\nType top-2: (A) Clinical/Intervention — supported by explicit clinical grouping (phantom limb pain vs amputee controls vs intact controls) and few-shot convention (dementia resting-state labeled Clinical/Intervention); (B) Resting-state — supported by the fact the paradigm is resting-state EEG.
