Defining an Event_Sequence as a single command parameter. The parameter Event_Sequence is used in many of the Events and Metrics commands. This is an extension to defining a Start Event and Stop Event that indicate which frames should be processed (i.e. LHS (left heel strike) to LHS).

This option provides the flexibility to set offsets on the Event_Sequence and to embed an Event Sequence inside another event. The following image shows the Define Event Sequence dialog box in the application, rather than doing this manually, we can achieve the same functionality using the command pipeline.

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=RSTANCE
/EVENT_SEQUENCE=RON+ROFF
! /EXCLUDE_EVENTS=
! /INSIDE_OF_SEQUENCE=
/OFFSET_FROM_START=-1
! /OFFSET_FROM_END=
/OFFSET_BY=FRAMES
/EVENT_SEQUENCE_INSTANCE=0
;

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.
