### BCI2000 Offline Analysis

Posted:

**10 Dec 2009, 16:24**Hi,

I have some questions/confusions in mind please help. Apologies for excess of questions.

1) Does somebody know, what Mathematical algorithms/methods and theory are used to generate Feature plots, topographis and waveforms?

2) In feature plots for p300 potential (time Vs Channels) we are required to look for high concentration values of r(squared). Also in mu Rhythm...Does some body know the theoratical background of r(squared)?.

3) Regarding BCI2000 filters pipe...In linear classifier, feature weights are generated using P300Classfier for P300 based BCIs. How can we generate feature weights for mu rhythms?

4) Also, linear classifier uses Step wise linear discriminant analysis for classification purposes. Does some body know about any other classification algorithms that has been used in BCI2000 filter pipe?

Please share any information. Many Thanks.
