The current dataset’s task name “BallSqueezing” strongly suggests an explicit movement execution paradigm; unlike the example, there is no explicit mention of visual/auditory stimuli, so the convention suggests mapping to Modality=Motor and Type=Motor based on the movement-focused task.","metadata_analysis":"Available metadata is sparse. Key facts:\n1) Title indicates the dataset identity: \"title\": \"BallSqueezingHD\".\n2) The task list explicitly names the paradigm: \"tasks\": [\"BallSqueezing\"].\n3) Only sample size is given: \"participants_overview\": \"Subjects: 12\".\nNo metadata explicitly states a clinical diagnosis/population or any sensory stimulus modality (visual/auditory/tactile cues).","paper_abstract_analysis":"No useful paper information.","evidence_alignment_check":"Pathology:\n- Metadata says: \"BallSqueezingHD\" and \"Subjects: 12\" (no diagnosis terms like Parkinson’s, TBI, epilepsy, etc.).\n- Few-shot pattern suggests: do not infer pathology without explicit recruitment/diagnosis statements.\n- Alignment: ALIGN (both indicate insufficient evidence) → choose Unknown.\n\nModality:\n- Metadata says: task is \"BallSqueezing\".\n- Few-shot pattern suggests: movement paradigms map to Motor modality when no dominant external sensory stimulus is described.\n- Alignment: ALIGN → choose Motor.\n\nType:\n- Metadata says: task is \"BallSqueezing\" (movement execution implied).\n- Few-shot pattern suggests: movement execution/imagery studies map to Type=Motor.\n- Alignment: ALIGN → choose Motor.","decision_summary":"Top-2 candidates per category with head-to-head comparison:\n\nPathology:\n1) Unknown — Evidence: no explicit clinical recruitment info; only \"BallSqueezingHD\" and \"Subjects: 12\".\n2) Other — Weak alternative if “HD” implied a specific condition, but this is not explicitly stated anywhere in provided metadata.\nDecision: Unknown (metadata does not state any pathology). Confidence reflects lack of explicit evidence.\n\nModality:\n1) Motor — Evidence: \"tasks\": [\"BallSqueezing\"] implies motor action is the primary input/command.\n2) Visual — Alternative if there were visual cues/targets (common in motor tasks), but no such stimulus is described.\nDecision: Motor. Confidence moderate because task name supports motor but no detailed stimulus description is provided.\n\nType:\n1) Motor — Evidence: \"BallSqueezing\" is a movement task; few-shot motor-movement example maps such paradigms to Type=Motor.\n2) Other — Alternative if ball squeezing were used as part of an intervention/clinical strength assessment, but no such aim is stated.\nDecision: Motor. Confidence moderate due to limited metadata.\n\nConfidence justification: Pathology low (no diagnosis quotes). Modality/Type rely on a single explicit task-name quote plus strong convention from the motor-task few-shot example."}},"computed_title":"BallSqueezingHD","nchans_counts":[{"val":200,"count":36}],"sfreq_counts":[{"val":8.719308035714286,"count":36}],"stats_computed_at":"2026-04-22T23:16:00.308687+00:00","total_duration_s":null,"author_year":"Gao2024","canonical_name":null}}
