Specify an Event Label(s) at the Global Maximum of a signal.
The result will be one maximum value over the range.
If the local maxima are needed, see the Event_Maximum command
To review the difference between local and global maximum values please see here.
Version 6
The Event_Global_Maximum command may be used to place an event at the Global maximum value of a signal. If Threshold has a value or expression only global maximum greater than the threshold will be identified.
Version 5
The Event_Global_Maximum command may be used to place an event label at the Global Maximum value of a signal.

Examples
This command may be used to create an event, RKFlex_Max, at the GLOBAL maximum value of a signal.
1) The maximum value of the signal may be over the entire signal
2) The maximum value of the signal may be during an event sequence
3) A specific event sequence may be excluded
Create an event RKFlex_Max at the maximum knee flexion angle during the gait cycle. The gait cycle is indicated by the RHS events.
NOTE: If no events are specified in the Event Sequence, a global maximum over the whole trial will be created.
One event will be created during each gait cycle.
Event_Maximum command may be used to create multiple maximum events during an event sequence.
Example - Dialog Box
To create the RKFlex_Max event using the Event_Global_Maximum dialog box:
| 1. Enter information into dialog box: Event_Name: RKFlex_Max Select Frame Offset:0 Signal Components:X Select an event sequence and Instance for the range: Event Sequence Instance:0 Defined Events:RHS + RHS Click OK |  |
| 2. Select desired signal: Select signal from data tree Right_Knee_Angle Click Import Selected Signals |  |
Two instances of RKFlex_Max were created, one in between each sequence of RHS+RHS.
 |
Example - Exclude Sequence
| Exclude Sequences containing these events can be used to exclude a specific sequence. In this example an event BAD was created between one sequence of RHS + RHS. Using the same parameters as the previous example, set the Exclude Sequences containing events parameter to BAD |  |
Only one RKFlex_Max event was created because the second sequence containing the event BAD was excluded:
 |
Example - Subsequence
| Subsequences can be used to create an event that occurs within a sequence within a sequence. In this example RKFlex_Max was created as the maximum value between LTO + LHS when these events feel between the RHS events. Using the same parameters as the previous example, set the Subsqeuence parameter to LTO + LHS |  |
RKFlex_Max event was created between RHS events that contained the LTO to LHS subsequence.
