Why is my Kinect metadata struct different?

I have the Kinect for Xbox One with the adapter for Windows, and I am running r2017a.
When I use getdata from the depth videoinput object, I get a 10 x 1 struct that looks different from the one here. https://www.mathworks.com/help/imaq/acquiring-image-and-skeletal-data-using-the-kinect.html?requestedDomain=www.mathworks.com
depthVid = videoinput('kinect',2,'Depth_512x424');
start(depthVid);
[~, ~, metadata] = getdata(depthVid);
metadata =
10×1 struct array with fields:
AbsTime
BodyIndexFrame
BodyTrackingID
ColorJointIndices
DepthJointIndices
FrameNumber
HandLeftConfidence
HandLeftState
HandRightConfidence
HandRightState
IsBodyTracked
JointPositions
JointTrackingState
RelativeFrame
TriggerIndex
I especially need the IsSkeletonTracked field, but I am not sure why it is not listed.

Hi! is because you checked the metadata from the kinect V1 and you are using the kinect v2 in this case the "IsBodyTracked" property is the same as "IsSkeletonTracked", also the parameters changed and you only have to write "on" to activate the property. This link indicates the properties of kinect v2 for skeleton data:

Hello. Maybe "IsBodyTracked" is the same property that "IsSkeletonTracked".
