====== Event Global Maximum ======
==== Overview ====
This command identifies the global maximum of a specified signal within a given time range and creates an event at that peak value. This command is useful for detecting peak joint angles, force plate data peaks, or maximum velocity in motion capture trials.
==== Pipeline Command ====
The following command shows the most recent update, **Version 6**.

==== Command Parameters ====
The following table shows the command parameters and descriptions:
|**/RESULT_EVENT_NAME=** |Specifies the name of the event created at the peak signal value.|
|**! /SIGNAL_TYPES=** |Type of signal from which the maximum value will be extracted (Target, Analog, etc.)|
|**! /SIGNAL_FOLDER=ORIGINAL** |Folder within signal type.|
|**! /SIGNAL_NAMES=** |Defines the signal from which the maximum value will be extracted.|
|**! /SIGNAL_COMPONENTS=** |Component of the named signal which the maximum value will be found in (X, Y, Z)|
\\
**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 [[Visual3D:Documentation:Pipeline:Event_Commands:Event_Maximum|Event_Maximum]] command\\
**\\
To review the difference between local and global maximum values please see [[Visual3D:Documentation:Pipeline:General_Information:Global_vs_Loca_Max_and_Min|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** | {{:Event_Global_Max_RKFlex_Max.jpg}}|
\\
|**2. Select desired signal:**\\ \\ Select **signal from data tree** Right_Knee_Angle\\ \\ Click **Import Selected Signals** | {{:Event_Global_Max_RKFlex_Max_Import.jpg}}|
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**\\ | {{:Event_Global_Max_RKFlex_Max_Exclude.jpg}}|
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**\\ | {{:Event_Global_Max_RKFlex_Max_Subsequence.jpg}}|
**RKFlex_Max** event was created between **RHS** events that contained the **LTO to LHS** subsequence.
