Hi ! I was wondering if there a way to access the "true" target position of a moving target (defined by the VCODE) in the DATA (c3d) structure ? When I replay a session through dexterit-e explorer, the moving target is being displayed so I assume the instantaneous VCODE is being saved somewhere, but I cannot find the corresponding field in DATA.
Thank you!
Nicolas

Hi, actually, could you point me to the exact task you referred to as "our visuomotor task"; I am having trouble understanding how to route a VCODE to the analog_inputs of the DataLogging block, so having an example would be helpful, thanks !

I see thank you. I'm still in the pilot phase so I will fix my code to output the position as an analog. Thank you !

The vcode is there but it isn’t easily accessible – it’s in a highly compressed format.
What you should do is save the position as an analog channel (you can see our visuomotor sample task on how to do that) so that you have that data available in your data file in an accessible way.
If you’ve already collected some subject data and need that information for analysis after the fact, you can send the data to us and we can look at extracting it. It’d be something to be done on a data file basis, so if you have lots of these, I don’t think we can help
You can find the visuomotor task I mentioned here: https://kinarm.com/examples/visuomotor-rotation-task/
