Error in User Tutorial:BCI2000 Tour:Mu Tutorial

Post by Mahelita » 23 Jan 2013, 07:54

Hi All,

just reporting that there is an error in the User Tutorial:BCI2000 Tour:Mu Tutorial ( http://www.bci2000.org/wiki/index.php/U ... I2000_Tour ) when using the lastest BCI2000 version (downloaded on 2012.01.22).
In the Parameter Files section, the user is told to load the parms/fragments/amplifiers/SignalGenerator.prm and parms/mu_tutorial/MuFeedback.prm parameter files but those files are actually wrongly configured and produce following error:
SpatialFilter::Preflight: The input signal's number of channels (4) must match the number of columns in the SpatialFilter parameter (8)
Not loading the parameter files after opening batch/CursorTask_SignalGenerator.bat solves the error.
It might be good to edit the wiki to remove the parameter loading steps.

Best,
Lukas

Hi,

thanks for the notification. The MuTutorial parameter file sets SpatialFilterType to CAR, so it should produce that error message.

Being able to reproduce the problem myself, I think this is a recent bug in BCI2000. I'll fix it ASAP.

Regards,
Juergen
