P300 Classification Data Collection

[doug.davies]

Hi all,

I am working on an application that works in the P300 Paradigm, but instead of selecting a single stimuli, I would like to generate a listing of the selection probabilities for each stimuli presented.

Can anyone provide me with some suggestions here?

The application is descended from StimulusPresentation, and currently in the OnClassResult function I am storing each value to which the state SelectedStimulus is set, and then using this as a data set. This only generates a few data points per run, though, and I am looking for a way to generate a more comprehensive data set.

Thanks,
Doug Davies

From what I understand, you want to have more classification results. You can configure BCI2000 to calculate a classification after each stimulus presentation, and not after presentation of n stimuli.

Just set NumERPsToAverage from 15 to 1.
