B-Alert in AcqKnowledge 4.4.1 and earlier: Attempting to record data after disabling the “Use B-Alert Definition File” option generates an “acquisition cannot continue” error message.
This issue can occur under the following circumstances:
This error occurs because when a definition file is assigned, calculation channels C0-C7 are automatically enabled to accommodate the Brain State Gauge data. If the “Use B-Alert definition file” is subsequently disabled, these calculation channels remain active even though the definition file is no longer being referenced. If this issue occurs, the following work-arounds are available:
A. Enable the “Use B-Alert Definition File” option and rerun the acquisition.
B. If the definition file is not to be used, disable calculation channels C0-C7 prior to recording:
