Using a Template allows you to determine where your force platforms are in relation to your camera system without repeating the entire CalTesterPlus platform protocol each time. In order to use this function you need to have a set of permanent markers (i.e. a template) which have a consistent position relative to the force platform. | Using a Template allows you to determine where your force platforms are in relation to your camera system without repeating the entire CalTesterPlus platform protocol each time.

The first step required when using CalTesterPlus to identify a Template is to locate the Template targets in the force platform coordinate system. For this reason both the CalTester rod and the Template must exist in these trials. The CalTester rod will be used to identify the center of pressure and the Template will be used to locate the targets. | The first step required when using CalTesterPlus to identify a Template is to locate the Template targets in the force platform coordinate system.

- For each trial, the CalTester Rod will be placed in various locations on the force platform. The average center of pressure applied by the CalTester Rod will be used to identify the location of the force platform in reference to the Template. The more spread out along the force platform, the more accurate the optimization will be. | - For each trial, the CalTester Rod will be placed in various locations on the force platform.

**NOTE:** The Selected Force Platform defaults to FP1 based on the C3D files that were loaded into the workspace. This is one of several reasons that a template must be created for FP1 and FP2 separately. | **NOTE:** The Selected Force Platform defaults to FP1 based on the C3D files that were loaded into the workspace.
