-{{event_labels are defined by the c3d format. event_labels exist only at motion capture frames (e.g. at point rate). for model based kinematic and kinetic calculations this is fine, because these signals only exist at motion capture frames.
+====== Metric Time of Maximum from Event ======
+====Overview====
+The **Metric Time of Maximum from Event** command can be used to compute the time between an event and a maximum signal. For example, this command could be used to determine the time between initial foot contact with the ground and max grf. The command can be found in the **Pipeline Workshop** under **Metric**.
-for measures of timing that involve signals that are at analog rate (e.g. force platform data) the motion capture rate isn't sufficient.
+====Pipeline Command====
-in version 5 a series of metric commands were introduced to identify the time of a threshold crossing or maximum at the analog rate.
+The command syntax is as follows:

+The dialog box allows you to assign values to the command parameters outlined above.
+====Notes====
+Event_Labels are defined by the c3d format. Event_Labels exist only at Motion Capture frames (e.g. at Point Rate). For model based kinematic and kinetic calculations this is fine, because these signals only exist at Motion Capture frames.
+For measures of timing that involve signals that are at ANALOG rate (e.g. Force Platform data) the motion capture rate isn't sufficient.
+In Version 5 a series of metric commands were introduced to identify the time of a threshold crossing or maximum at the analog rate.
