"instruction": "Analyze DEAP trial `6` and compare the trial-relative candidate intervals:\n\n- `A`: `[8, 12)`\n- `B`: `[24, 28)`\n- `C`: `[40, 44)`\n\nFor each candidate interval, use the immediately preceding and following\n4-second intervals as references. Combine the two reference intervals and use\ntheir median sample value as one common reference center. For every channel in\nthe following three modality groups, measure the root-mean-square deviation\nfrom this center in the candidate and reference intervals, normalize the\ncandidate disturbance by the average disturbance of the two references, and\naggregate channel scores using their median:\n\n- frontal EEG: `Fp1`, `Fp2`, `AF3`, `AF4`;\n- EOG: `EXG1`, `EXG2`;\n- EMG: `EXG3`, `EXG4`.\n\nUse the aggregated EEG score to select the candidate with the largest frontal\nEEG disturbance. Treat the disturbance as clear only when its score is at\nleast `1.25` and at least `20%` larger than the second-highest EEG score.\n\nFor the selected candidate, compare the aggregated EOG and EMG support scores.\nReport `EOG` only when the EOG support score is at least `1.25` and at least\n`10%` larger than the EMG score. Report `EMG` under the analogous condition.\nOtherwise report `neither`. If the EEG disturbance is not clear, report\n`neither` regardless of the EOG and EMG scores.\n\nReport only `selected_candidate` and `supporting_modality`."
