B-Alert Gauges Unresponsive

B-Alert in AcqKnowledge 4.4.1 and earlier: Brain State Gauge Surface and Heat Maps are unresponsive during acquisition; colors remain a uniform green (Surface Map) and yellow (Heat Map).

B-Alert-Gauge-color

This is most likely because the “No output into ABM format” option is selected in the B-Alert Data Acquisition Settings. In order for Surface and Heat Map output to be recorded, a valid ABM data file output location must be defined.

Use the following steps to ensure proper Surface and Heat Map operation:

  1. Choose B-Alert menu > Set Up Data Acquisition > Length/Rate.
  2. Click the “Choose ABM data file location” button.
  3. Select the “Output data into ABM data file at:” option, assign a valid file path, and click OK.
  4. Rerun the B-Alert acquisition. The Surface and Heat Map gauges should display the expected color output.
