(2) The pediatric epilepsy sleep/HFO dataset (Pathology=Epilepsy) provides a convention that iEEG/clinical intracranial recordings are commonly associated with epilepsy recruitment, but this is only a contextual hint (not a metadata fact) for the current dataset. For Type, the schizophrenia visual discrimination example (Type=Perception) supports mapping stimulus-driven sensory paradigms to \"Perception\" (even if the task is not a classic discrimination), which aligns with a movie/audiovisual stimulation setting.","metadata_analysis":"Key metadata available is only the README text.

(2) \"Full description of the data in our dataset paper: https://www.nature.com/articles/s41597-022-01173-0\".

Few-shot pattern SUGGESTS intracranial/iEEG datasets often involve epilepsy patients (see epilepsy HFO example), but this is an inference.

Few-shot pattern SUGGESTS labeling combined auditory+visual paradigms as \"Multisensory\" (cross-modal oddball example). ALIGN: yes.\nType: Metadata SAYS \"stimulation with a short audiovisual film\" implying sensory/naturalistic stimulus processing. Few-shot pattern SUGGESTS sensory-stimulus paradigms map to \"Perception\" (e.g., visual discrimination; auditory perception examples). ALIGN: yes.","decision_summary":"Top-2 candidates per category:\n\nPathology:\n1) Epilepsy — Evidence: the dataset is explicitly \"iEEG-fMRI\" (\"Open iEEG-fMRI dataset...\"); iEEG typically implies invasive electrodes used in pre-surgical epilepsy evaluation (contextual, not explicitly stated here). Alignment: metadata silent; decision based on reasonable contextual inference.\n2) Unknown — Evidence: no explicit diagnosis/recruitment criteria in provided snippet.\nFinal: Epilepsy (winner due to strong contextual linkage of iEEG datasets to epilepsy cohorts, but with limited explicit support).\n\nModality:\n1) Multisensory — Evidence: \"a short audiovisual film\" indicates both auditory and visual stimulation; few-shot cross-modal oddball convention maps combined modalities to Multisensory.\n2) Visual — Alternative if film-viewing were treated as primarily visual, but contradicted by explicit \"audiovisual\".\nFinal: Multisensory.\n\nType:\n1) Perception — Evidence: \"stimulation with a short audiovisual film\" is primarily sensory stimulus processing/naturalistic viewing/listening.\n2) Other — Possible if the main goal were, e.g., method development or multimodal alignment (iEEG-fMRI) rather than a perceptual construct; however no such aim is stated in the snippet.\nFinal: Perception.\n\nConfidence notes tied to evidence: Modality and Type each have 1 explicit supporting quote (\"audiovisual film\").
