 ===== Overview ===== ===== Overview =====
-The **Event_Threshold** command is used to detect threshold crossings (when signal crosses a specified value) in biomechanical signals and label events accordingly. This command provides extensive control over event placement by allowing users to define frame or time offsets, include or exclude sequences, and refine detections using component selection and event constraints.+The **Event_Threshold** command is used to detect threshold crossings (when signal crosses a specified value) in signals and label events accordingly.

 This command is particularly useful for defining critical events based on signal thresholds, such as peak force occurrences, velocity changes, or acceleration-based triggers. This command is particularly useful for defining critical events based on signal thresholds, such as peak force occurrences, velocity changes, or acceleration-based triggers.

 +  * **New Event Label Name**: Name to assign event that reaches threshold value.
 +  * **Signal Component**: Direction of signal to use (X, Y, Z, ALL)
 +  * **Frame Window**: Number of frames to check for threshold condition.
 +  * **Frame Offset**: Shift event by a specified number of frames.
 +  * **Time Offset**: Shift event by time (in seconds).
 +  * **Threshold**: Value the signal must cross to trigger the event.
 +  * **Event Instance**: Specify which instance of the event to label. (0 = all)
 +  * **Label on Ascent/Descent**: Choose to place event when threshold is cross in an increasing signal (ascent) or decreasing signal (descent).
 +  * **Ensure Window Before/After**: Full frame window is available before or after detected point to avoid errors.
 +  * **Event Sequence**: Specify range in which to search for threshold crossings.
 +  * **Event Subsequence**: Specify subrange in which to search for threshold crossings.
