 ====== Event Global Maximum ======
-\\
+===== Overview =====
-**Specify an Event Label(s) at the Global Maximum of a signal.**
+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.
+  * The result will be one maximum value over the range.
-**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]]
-**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.

+===== Command Parameters =====
+The following table shows the command parameters and descriptions:
-This command may be used to create an event, **RKFlex_Max**, at the GLOBAL maximum value of a signal.\\
+|**Parameter**                     |**Description**|
-) The maximum value of the signal may be over the entire signal\\
+|**/RESULT_EVENT_NAME=**           | Name of the event that will be created at the frame where the signal reaches its global maximum. |

+===== Dialog =====
-Create an event RKFlex_Max at the maximum knee flexion angle during the gait cycle. The gait cycle is indicated by the RHS events.\\
+The command can be edited in a text editor or in a dialog form. To edit in the dialog pop-up form either click on the **Edit** button in the pipeline workshop or double-click on the command. The dialog box is shown below:
-**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.\\
+{{:visual3d:documentation:pipeline:event_commands:egm_dialog.png?500|}}
-=== Example - Dialog Box ===
+  * **New Event Label Name**: Name for the event that will be created at the global maximum.
+  * **Signal Component**: Signal direction selection (X, Y, Z).
+  * **Frame Offset**: Number of frames to shift the created event forward or backward from the maximum point.
+  * **Time Offset**: Shifts event by time (in seconds).
+  * **Threshold**: Min. signal value required to accept a maximum.
+  * **Event Sequence and Instance for range**: Search for maximum based on event ranges.
+  * **Subsequence and Instance within the Event Sequence**: Search inside a sub-range within the event sequence.
-To create the RKFlex_Max event using the Event_Global_Maximum dialog box:
+===== Examples =====
+The following example will go through the use of the **Event_Global_Maximum** command in the Visual3D application.
+This command may be used to create an event RKFlex_Max at the maximum knee flexion angle during the gait cycle. The gait cycle is indicated by the RHS events. This example will go through different use cases of this command:
 \\
-|**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}}|
+**Example 1)** The maximum value of the signal may be over the entire signal
 \\
+**Example 2)** The maximum value of the signal may be during an event sequence
+\\
+**Example 3)** A specific event sequence may be excluded
-|**2. Select desired signal:**\\ \\ Select **signal from data tree** Right_Knee_Angle\\ \\ Click **Import Selected Signals**  |  {{:Event_Global_Max_RKFlex_Max_Import.jpg}}|
+**NOTE:** If no events are specified in the Event Sequence, a global maximum over the whole trial will be created.\\
-Two instances of **RKFlex_Max** were created, one in between each sequence of **RHS+RHS**.\\
+==== Example 1: Simple Use Case ====
+This example will be done showing both the dialog box and corresponding command text.
