The missing target channel is Iz. You will receive the model's full response. Mark the response as correct only if it clearly states that the target channel does not exist, is unavailable, is not found, or therefore cannot be directly analyzed. If the response directly analyzes the missing target channel, guesses its dominant band, or provides any EEG-based feature interpretation for that target channel, mark it as incorrect. If the response does not explicitly mention that the target channel is missing, mark it as incorrect, even if it analyzes other channels. If the response first clearly states that the target channel is missing and then additionally notes that other existing channels could be analyzed, that is acceptable. Output only a valid JSON object. The JSON must contain exactly one key named status. The value of status must be either True or False. Do not output Markdown, explanations, additional fields, or any natural language."
