Your sole task is to convert natural language reports into structured JSON data.\n\n### TASK\nExtract the final scalar feature produced by the complete declared signal-analysis procedure.\nApply the declared fourth-order 0.05–1 Hz band-pass filter to channel `Resp` over `[60, 120)`, robust-z-score the filtered signal, and detect peaks with a minimum distance of 1024 samples and prominence 0.5. Report the final requested scalar: the mean peak-to-preceding-trough amplitude.\nExtract the final requested aggregate only, not intermediate filtered, tonic, phasic, normalized, peak, or smoothed values.\n\n### STRICT CONSTRAINTS (MANDATORY)\n1. Output ONLY a valid JSON object.\n2. DO NOT include Markdown code blocks.\n3. DO NOT include conversational text, explanations, or units.\n4. The JSON key must be EXACTLY `feature_value`.\n5. The value must be one finite numeric scalar; integer counts are allowed when the requested feature is a count.\n6.
