Configuring 2D cursor Task: need vertical cursor

[Goxothorn]

Hello,
In my master thesis project I'm using the 2D cursor task. In this task, by default the cursor is going from left to right but I would need it to go from down to up. I checked how I could do that in the setting and i find how to modify the starting position of the cursor but not how to change its course.
Thank you for your help.

It depends on the version of the application you're using. One way I can imagine doing it with the version I have is to make my first control signal a constant (i.e. 1) and the second control signal will be your brain signal.
