 - **Timeout:** recovery time after a pulse is sent (in milliseconds).
 - **Calibration:** calibration time before the experiment to setup the signals normalization (in seconds). One minute is usually enough.
 - **Threshold:** probability threshold for the detections. Between 0 and 1.
+- **Drift:** number of standard deviations above which the signal is considered to be dominated by extreme offset drift and the CNN will not predict.
 - **Output:** output channel for TTL pulses.
