User Tutorial:Interpreting the Results: Difference between revisions

In User Tutorial:Performing an Offline Analysis of EEG Data, we used BCI2000 Offline Analysis to generate a feature plot, topographies and spectra for the eeg1 sample data comprising the data files eeg1_1.dat, eeg1_2.dat and eeg1_3.dat. In this continuation of the tutorial, we'll compare our results from User Tutorial:Performing an Offline Analysis of EEG Data to analyses of other data from the same subject.

Imagined vs. Real

In User Tutorial:Performing an Offline Analysis of EEG Data, we used the eeg1 sample data that was recorded for a single subject responding to separate instructions to move both feet, both hands and rest. In BCI, we typically desire to be able to communicate with an external device without actual movement. Fortunately, results

 In [[User Tutorial:Performing an Offline Analysis of EEG Data]], we used ''BCI2000 Offline Analysis'' to generate a feature plot, topographies and spectra for the eeg1 sample data comprising the data files <tt>eeg1_1.dat</tt>, <tt>eeg1_2.dat</tt> and <tt>eeg1_3.dat</tt>.  In this continuation of the tutorial, we'll compare our results from [[User Tutorial:Performing an Offline Analysis of EEG Data]] to analyses of other data from the same subject.
-We will also be using the eegImag1.dat, eegImag2.dat and eegImag3.dat sessions.  These sessions are labeled similarly but instead of actual movement, the subject was instructed to imagine performing the given instruction (e.g., imagine moving both feet).
