Hi,

the cursor task appearance may be 3D, but the tutorial setup is actually 2D, i.e. there is no cursor movement in Z direction. The CursorTask page on the BCI2000 wiki will tell you how to switch from 3D to 2D appearance if this is what you would like to do.

Also, there is an example on the CursorTask wiki page that will show you how to set up 1D feedback.

The "help" button in the BCI2000 configuration provides an easy way to navigate to a local copy of the BCI2000 wiki, and open the information regarding a certain parameter. Just click the "help" button once, and then click the name of the parameter in question.

In general, the recommended way to search for answers is to use the Google site search field on
http://www.bci2000.org/wiki/
Make sure to use the field and button at the top center, not the one at the top right, which is restricted to the wiki. Also make sure to enter words exactly as they appear in the BCI2000 configuration dialog, otherwise the search may fail.

You are welcome to contribute a video version of the tutorials if you think this might benefit other users.

Best regards,
Juergen

Hi,

the error message says that you don't have enough data for the condition StimulusCode == 0. You will need to increase the inter-stimulus-interval (ITI) of your stimulus presentation to fix that.

hello ditalupita,

I am also trying to perform the same task using emotiv. Please let me know the values you entered into the source tab of the configuration window. It would be of great help.
