File Save

The File_Save command is used to save the current state of the active CMZ file in Visual3D.

• Functions the same way as click a “Save” button: it commits any pipeline-based changes to the currently opened CMZ file.
• If no CMZ file is active (e.g., untitled or no file has been opened), Visual3D will prompt the user to specify the file name and location for saving.

Important Note: This command is for saving over the currently open CMZ file, not creating a new one (“Save As”).

The command below is as seen on the Visual3D application, it has parameters as there are options to manipulate in this command:

File_Save
/SET_PROMPT=Save CMZ file
;

The following table shows the command parameters and descriptions.

Due to the simplicity of this command, there is no dialog box with editable fields like other commands.

• The only editable parameter is the optional prompt shown in the save dialog.

The following examples will go through the use of the File_Save command in the Visual3D application.

This example loads a CMZ file, runs automatic gait event detection, and then saves the modified file.

Step 1: Open a file, the name/path will need to be filled in by the user, if not specified, a prompt will open for user to select CMZ.

File_Open
!/FILE_NAME=
!/FILE_PATH=
!/SEARCH_SUBFOLDERS=FALSE
!/SUFFIX=
!/SET_PROMPT=Open Trial
!/ON_FILE_NOT_FOUND=PROMPT
!/FILE_TYPES_ON_PROMPT=
;

Step 2: Add Gait Events (kinetic data)

Automatic_Gait_Events
!/FRAME_WINDOW=8
!/USE_TPR=TRUE
!/TPR_EVENT_INSTANCE=1
;

Step 3: Save File

File_Save
!/SET_PROMPT=Save CMZ with gait events
;

This example loads a file, adds a custom event using Event_Global_Maximum, computes the metric value at this event, then saves the trial with all modifications.

File_Open
!/FILE_NAME=Participant04
!/FILE_PATH=CMZ_Data
!/SEARCH_SUBFOLDERS=TRUE
!/SUFFIX=_Walk1.cmz
!/SET_PROMPT=
!/ON_FILE_NOT_FOUND=SKIP
!/FILE_TYPES_ON_PROMPT=
;

Event_Global_Maximum
/RESULT_EVENT_NAME=Peak_LeftKneeFlex
/SIGNAL_TYPES=LINK_MODEL_BASED
/SIGNAL_FOLDER=ORIGINAL
/SIGNAL_NAMES=Left_Knee_Angle
/SIGNAL_COMPONENTS=Z
/FRAME_OFFSET=0
/TIME_OFFSET=
/EVENT_SEQUENCE=RTO,RHS
/EXCLUDE_EVENTS=
/EVENT_SEQUENCE_INSTANCE=0
/EVENT_SUBSEQUENCE=
/SUBSEQUENCE_EXCLUDE_EVENTS=
/EVENT_SUBSEQUENCE_INSTANCE=0
/THRESHOLD=
;

Metric_Signal_Value_At_Event
/SIGNAL_FOLDER=ORIGINAL
/SIGNAL_LABEL=Left_Knee_Angle_Z
/EVENT_NAME=Peak_LeftKneeFlex
/RESULT_METRIC_NAME=KneeFlexion_Max
;

File_Save
!/SET_PROMPT=Save updated CMZ with metrics
;

• File_Save should be placed at the end of your pipeline unless intermediate saves are being made.
• If batch processing, always verify the file opened with 'File_Open' is correctly matched to the save logic.
