+=====Event TPR File=====
+=====Overview=====
+The Event_TPR_File command is used to match a pre-saved signal pattern to a signal in the
+current selected trial. When the shape of the signal matches the pattern, an event is created at that frame.
+  * It is typically used to validate and test pattern recognition templates when build TPR files for broader use across multiple trials.
+  * The signal that the pattern is being matched to must exist in the trial.
+=====Pipeline Command=====
+The command below is as seen on the Visual3D application, it has many parameters as there are many options to manipulate this command:
+<code>
+Event_TPR_File
+! /SIGNAL_TYPES=
+! /SIGNAL_FOLDER=ORIGINAL
+! /SIGNAL_NAMES=
+/EVENT_NAME=
+! /SELECT_X=FALSE
+! /SELECT_Y=FALSE
+! /SELECT_Z=FALSE
+/FILE_NAME=
+! /TOLERANCE=20.0
+;
+</code>
+=====Command Parameters=====
+The following table shows the command parameters and descriptions:
+|**Parameter**        |**Description**|
+|**/SIGNAL_TYPES=**   | Type of signal being evaluated (e.g., `LINK_MODEL_BASED`, `ANALOG`). |
+|**!/SIGNAL_FOLDER=** | Folder where the signal is located (`ORIGINAL`, `FILTERED`, etc.). |
+|**/SIGNAL_NAMES=**   | Name of the signal to be evaluated (e.g., `Right_Ankle_Accel`). |
+|**/EVENT_NAME=**     | Name of the new event that will be created when a match is found. |
+|**!/SELECT_X=FALSE** | Use the X-component of the signal (set to `TRUE` if relevant). |
+|**!/SELECT_Y=FALSE** | Use the Y-component (e.g., for vertical acceleration). |
+|**!/SELECT_Z=FALSE** | Use the Z-component (e.g., for forward/backward motion). |
+|**/FILE_NAME=**      | Full name of the `.tpr` file containing the pattern template. |
+|**!/TOLERANCE=20.0** | The matching threshold. Lower values = stricter match (e.g., 10.0 = tight match). |
+=====Dialog=====
+The dialog for this command simplifies pattern-based event creation:
+{{:visual3d:documentation:pipeline:event_commands:event_tpr_file_dlg.png?400|}}
+Interface elements:
+  * **TPR File**: A browse option to load in the pattern file.
+  * **Event Name**: Define the event label to be generated.
+  * **Pattern Components to Match**: Select X, Y, and/or Z direction.
+  * **Tolerance**: Controls how strictly the signal must match the pattern. Smaller values mean tighter matching.
+=====Examples=====
+The following example will go through the use of the Event_TPR_File command within the Visual3D application.
+====Example 1: Assigning Events to Event-less Trial based on TPR====
+This command is not as intuitive for use as the Event_TPR_Signal when it comes to performing TPR on and placing events on specified signals.
+  * It is more useful for assigning events to the whole file if you have already generated a .tps file (target pattern signal) or you could also simply use events from another .c3d, like Event_TPR_Signal.
+  * An important thing to note is that this command is dependent on what is saved in the TPR file - which must be done properly using **Event_TPR_Signal** or **Event_Save_TPR_Signal**
+The following steps can be taken for this example:
+**1.** Make sure that you have a valid TPR file with the events and make sure that the same signal also exists in the current .c3d which has no events.
+**2.** In this example, a .c3d file will be used which has ALL automatically detected gait events.
+**3.** The following information can be entered, this is transferring the LHS events from the user selected file to the signal which was selected to be L Hip Angle.
+|{{:visual3d:documentation:pipeline:event_commands:event_tpr_exdlg.png?400|}}|<code>
+Event_TPR_File
+/SIGNAL_TYPES=LINK_MODEL_BASED
+! /SIGNAL_FOLDER=ORIGINAL
+/SIGNAL_NAMES=L Hip Angle
+/EVENT_NAME=LHS
+/SELECT_X=TRUE
+! /SELECT_Y=FALSE
+! /SELECT_Z=FALSE
+/FILE_NAME=[USER SELECTION]
+! /TOLERANCE=20.0
+;
+</code>|
+After running this pipeline command, the **LHS** Event should show up in the workspace.
