This command in Visual3D's pipeline allows users to define a sequence of events based on an ordered list of existing events, useful for identifying movement phases within a dataset. Essentially defining an Event_Sequence as a single command parameter, acting as an extension to defining a Start and Stop Event that indicate which frames should be processed.

The following shows the command to achieve the action of defining a start and stop event for which frames should be processed.

Event_Define_Event_Sequence
/EVENT_SEQUENCE_NAME=
! /EVENT_SEQUENCE=
! /EXCLUDE_EVENTS=
! /INSIDE_OF_SEQUENCE=
! /OFFSET_FROM_START=
! /OFFSET_FROM_END=
! /OFFSET_BY=PERCENT
! /EVENT_SEQUENCE_INSTANCE=
;

The following table shows the command parameters and descriptions:

After adding the Event_Define_Event_Sequence command into the pipeline on the Visual3D application, the user can double-click with the left mouse button in order to open the following dialog:

• Defined Events and Event Sequence, lists of available events in the dataset, and list of selected events that define the sequence, respectively.
• Event Sequence Instance: Defines which instance of the event sequence should be used.
• Range Start and End Offsets: Allows adjustments to where the sequence starts and ends.
• Define Sequence Inside of Outer Sequence: Allows for nested event sequences, meaning the defined sequence occurs within a broader sequence.

In this case, the event sequence will start one frame before the sequence RON+ROFF. The resulting signal can be used wherever an Event_Sequence is used.

For example, the use case in the Metric_Mean command. Instead of the following syntax:

Metric_Mean
/RESULT_METRIC_NAME=_MEAN
/APPLY_AS_SUFFIX_TO_SIGNAL_NAME=TRUE
! /RESULT_METRIC_FOLDER=PROCESSED
/SIGNAL_TYPES=LINK_MODEL_BASED
/SIGNAL_NAMES=RKNEE_ANGLE
! /SIGNAL_FOLDER=ORIGINAL
! /SIGNAL_COMPONENTS=ALL_COMPONENTS
/[[Visual3D:Documentation:C3D_Signal_Types:EVENT_LABEL_Data_Type#Event_Sequence|EVENT_SEQUENCE]]=RON+ROFF
/[[Visual3D:Documentation:C3D_Signal_Types:EVENT_LABEL_Data_Type#Exclude_Events|EXCLUDE_EVENTS]]=
! /GENERATE_MEAN_AND_STDDEV=TRUE
! /APPEND_TO_EXISTING_VALUES=FALSE
;

You could use the following line in replacement to achieve the same.

/[[Visual3D:Documentation:C3D_Signal_Types:EVENT_LABEL_Data_Type#Event_Sequence|EVENT_SEQUENCE]]=RSTANCE

NOTE: When using events in a command, the commands will iterate across subjects contained in the current workspace. As such, events being created should list the generic event label name, and as the event command iterates through subjects, it will create the subject specific events that are prefixed with the specific subject prefix.

In commands using event labels and event sequences to process data, the event labels and sequences listed to process between should be generic (without a subject prefix), and as each subject is processed, the event range/sequence specified will automatically use the specific events prefixed for each subject as they are processed.
