Hi,

I'm not sure whether I understand your question.
Please make sure that you followed the tutorial at
http://www.bci2000.org/wiki/index.php/U ... I_Tutorial
Once you have successfully finished that, you should have a working P300 speller BCI, with no further step required.

More information about the P300Classifier program, including references regarding the SWLDA classifier training method, may be found here:
http://www.bci2000.org/wiki/index.php/U ... Classifier

It may also be of interest that the SWLDA classifier training method is available in Matlab's stats toolbox. There, it is called stepwisefit:
