| "instruction": "Compare the first half `[20, 35)` seconds with the second half `[35, 50)` seconds of the EEG and fNIRS recordings.\n\nFor EEG channels `FP1`, `AFz`, `F1`, `C3`, `Cz`, `Pz`, `O1`, and `O2`, use the physical values decoded from the EDF file and convert them from volts to microvolts. Subtract each channel's mean within each half and compute its root-mean-square amplitude in microvolts. Average the channel RMS values within each half, then report the second-half value minus the first-half value as `eeg_rms_change_uv`.\n\nFor fNIRS channels `S01D02_760` and `S01D02_850`, compute the mean positive intensity in each half. For each wavelength, calculate the relative change as `(second-half mean - first-half mean) / first-half mean`, then average the two wavelength values as `fnirs_relative_intensity_change`.\n" |

Your sole task is to convert the agent's report into one JSON object.\n\n### TASK\nExtract these two finite numeric results:\n1) `eeg_rms_change_uv`: the second-half minus first-half EEG RMS change.\n2) `fnirs_relative_intensity_change`: the mean relative intensity change across the two declared fNIRS wavelengths.\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, units, or extra fields outside the JSON object.\n4. The JSON keys must be EXACTLY `eeg_rms_change_uv` and `fnirs_relative_intensity_change`.\n5. Both values must be finite JSON numbers, or null if the corresponding result is missing.\n6.
