Limit on # of coefficients in P300 LinearClassifier filter

Post by Ray Ma » 15 Jun 2010, 16:27

Hi,

The P300 LinearClassifier filter seems to only accept no more than 99 coefficients. I'm wondering whether it's possible to remove this hard limit to make use of more than 99 coefficients. Could anybody give me some suggestions?

Thanks very much!

Hi Ray,

go to BCI2000\src\core\Operator\OperatorQt\EditMatrix.ui, open it in a text editor, and change the two spin boxes' "maximum" properties from 99 to a higher value, then recompile the operator module.

The issue will be fixed in future versions of BCI2000.
