BCI2000 Matlab classification

Post by mkroesen » 07 Jan 2013, 08:24

Hi at all

Is there any Matlab-related software to load newer BCI2000-files into it? Because I've to know how the classifier is working exactly and there aren't enough informations about the P300_classifier.exe to redo classification in Matlab.

Thanks
Markus

Markus,

If you don't have the source code, then follow the instructions at the following link:
http://www.bci2000.org/wiki/index.php/P ... ource_Code

To load BCI2000 files into MATLAB, look in "BCI2000\tools\mex" for load_bcidat.m
Make sure to add the above folder to your Matlab path, then read the documentation for load_bcidat
You can find more information at the following link.
http://www.bci2000.org/wiki/index.php/U ... _MEX_Files

If all you want to do is figure out how P300Classifier works then take a look at its source code in
BCI2000\src\core\Tools\P300Classifier

If you are interested in P300 classification in general I suggest you read the following article:
