Event Global Maximum

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

The result will be one maximum value over the range.

If the local maxima are needed, see the Event_Maximum command

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

Version 6

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

Version 5

The Event_Global_Maximum command may be used to place an event label at the Global Maximum value of a signal.

Event_Global_Maximum /RESULT_EVENT_NAME= ! /SIGNAL_TYPES= ! /SIGNAL_NAMES= ! /SIGNAL_FOLDER= ORIGINAL ! /SIGNAL_COMPONENTS= ! /FRAME_OFFSET= 0 ! /TIME_OFFSET= ! /EVENT_SEQUENCE= ! /EXCLUDE_EVENTS= ! /EVENT_SEQUENCE_INSTANCE= 0 ! /EVENT_SUBSEQUENCE= ! /SUBSEQUENCE_EXCLUDE_EVENTS= ! /EVENT_SUBSEQUENCE_INSTANCE= 0 ! /EVENT_INSTANCE= 0 ! /SELECT_X= ! /SELECT_Y= ! /SELECT_Z= ! /SELECT_RESIDUAL= ! /START_AT_EVENT= ! /END_AT_EVENT= ;

Examples

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

Create an event RKFlex_Max at the maximum 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 maximum over the whole trial will be created.

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

Example - Dialog Box

To create the RKFlex_Max event using the Event_Global_Maximum dialog box:

1. Enter information into dialog box: Event_Name: RKFlex_Max 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

Two instances of RKFlex_Max were created, one in between each sequence of RHS+RHS.

Example - Exclude Sequence

Exclude Sequences containing these events can be used to exclude a specific sequence. In this example an event BAD was created between one sequence of RHS + RHS. Using the same parameters as the previous example, set the Exclude Sequences containing events parameter to BAD

Only one RKFlex_Max event was created because the second sequence containing the event BAD was excluded:

---

Example - Subsequence

Subsequences can be used to create an event that occurs within a sequence within a sequence. In this example RKFlex_Max was created as the maximum value between LTO + LHS when these events feel between the RHS events. Using the same parameters as the previous example, set the Subsqeuence parameter to LTO + LHS

RKFlex_Max event was created between RHS events that contained the LTO to LHS subsequence.
