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).
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.
Note that this issue is common only to AcqKnowledge versions 4.4.1 and earlier. In AcqKnowledge versions 4.4.2 and higher, Heat and Surface Map output will function properly with the “No output” option selected.
Use the following steps to ensure proper Surface and Heat Map operation:
Choose B-Alert menu > Set Up Data Acquisition > Length/Rate.
Click the “Choose ABM data file location” button.
Select the “Output data into ABM data file at:” option, assign a valid file path, and click OK.
Rerun the B-Alert acquisition. The Surface and Heat Map gauges should display the expected color output.
