Specify an Event Label(s) at the Global Minimum of a signal.

The result will be one minimum value over the range.

If the local minima are needed, see the Event_Minimum command

To review the difference between local and global minimum values please see here.

Version 6

The Event_Global_Minimum command may be used to place an event at the Global minimum value of a signal. If Threshold has a value or expression only global minimum less than threshold will be identified.

Examples

This command may be used to create an event, RKFlex_Min, at the GLOBAL minimum value of a signal.
1) The minimum value of the signal may be over the entire signal
2) The minimum value of the signal may be during an event sequence
3) A specific event sequence may be excluded


Create an event RKFlex_Min at the minimum knee flexion angle during the gait cycle. The gait cycle is indicated by the RHS events.
NOTE: If no events are specified in the Event Sequence, a global minimum over the whole trial will be created.

One event will be created during each gait cycle.
Event_Minimum command may be used to create multiple minimum events during an event sequence.

Example - Dialog Box

To create the RKFlex_Min event using the Event_Global_Minimum dialog box:


1. Enter information into dialog box:

Event_Name: RKFlex_Min
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

2. Select desired signal:

Select signal from data tree Right_Knee_Angle
Click Import Selected Signals

caption


RKFlex_Min will be created at the global minimum value during the gait cycle.

Other options within the command such as Exclude Event, and Select Subsequence are explained in detail on the Event_Global_Maximum page.



Version 4

Specify an Event Label(s) at the Global Minimum of a signal.


Event_Global_Minimum
/Signal_Types= The type of signal to be evaluated
/Signal_Names= The names of the signals to be evaluated
/Signal_Folder= The name of the signal folder
/Event_Name= The name to be given to the threshold event
/Select_X= (True or False)Use this component of the signal
/Select_Y= (True or False)Use this component of the signal
/Select_Z= (True or False)Use this component of the signal
/Radius= The range of frames of data that must be below the minimum
/Start_At_Event= The search begins from the start event
/End_At_Event= The search ends at the end event
