+ | ===== Minimum ===== | ||
+ | |||
+ | It is important to understand the differences between the **Event_Global_Minimum** and **Event_Minimum** commands. | ||
+ | |||
+ | **Event_Global_Minimum** creates an event at the global minimum value of a signal.\\ | ||
+ | \\ | ||
+ | **Event_Minimum** creates an event at the local minimum value of a signal. This means the minimum value must be the minimum value for a number of frames before and after the value.\\ | ||
+ | The minimum number of frames is specified in the **Frame Window** parameter of the pipeline command.\\ | ||
+ | \\ | ||
+ | \\ | ||
+ | \\ | ||
+ | \\ | ||
+ | |||
+ | |||
+ | ==== For Example: ==== | ||
+ | |||
+ | For example: Create events at the global and local minimum of the Right Knee Flexion Angle during a gait cycle (RHS+RHS). | ||
+ | |||
+ | | **[[Visual3D: | ||
+ | |||
+ | \\ | ||
+ | \\ | ||
+ | The **Global Minimum** event is created at the lowest flexion angle during the entire gait cycle.\\ | ||
+ | \\ | ||
+ | The **Local Minimum** event is created at the minimum flexion angle, if that pt is the minimum value for 8 frames (the number of frames is pecified by the frame window).\\ | ||
+ | \\ | ||

+ | \\ | ||
+ | To identify a local minimum:\\ | ||
+ | - The local minimum must be a peak and the signal may not be decreasing within the specified frame window. | ||
