+====== Global vs Loca Max and Min ======
+\\
+===== 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).

+\\
+\\
+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.
