Problem with cursor task

Post by RowanEEG » 23 Apr 2013, 13:53

Hello all, I recently set up my cursor task using a mix of tutorials online and I haven't figured out how to obtain the initial training session for data. I read that there are supposed to be arrows on screen to tell you which way to think, but the task itself with the ball comes up and doesn't seem to be controlled by the user at all.

This might not be enough information, so I can post more if it is needed.

Thank you for your time.

Just follow the BCI2000 mu rhythm tutorial, which is linked from the BCI2000 main wiki page.

yes, I did that, but it still doesn't bring me to the training stage when I follow the instructions.

As the tutorial says, run
batch/StimulusPresentation_<YourAmplifier>.bat
for the initial session, rather than
batch/CursorTask_<YourAmplifier>.bat

HTH,

Thanks for all the help, so far.

These cannot both be true at the same time. Are you saying that you can run the CursorTask with your Neuroscan amplifier but not StimulusPresentation?

yes sorry. I tried first running cursor task and i could not get the training stage. Then I tried running the stimulus presentation and received the error.

There is a known problem in your version of the NeuroscanClient, which should be fixed in r4284 on SVN. You might either compile that or a more recent version of the NeuroscanClient yourself, or you might wait until BCI2000 3.0.6 is released, which is overdue, and should be released within the next two months.

If this is not an option, restarting Neuroscan Acquire and/or tweaking its settings by switching from 16 to 32 bit and back might also help.

Regards,
Juergen

Do you know where I can find a fixed version of the Neuroscan client? or a tutorial that would help me compile a working one?

Go to
http://www.bci2000.org/wiki/
and there click Programming -> Quickstart Guide.
It's about building your own BCI2000 module, but it gives you all the information you need to get going with compiling BCI2000 as well.
