"replay" recorded data

Post by tcetin » 20 Aug 2010, 05:38

Dear BCI2000-People,

I would like tom "replay" some recorded data, i.e. record a P300-speller-Session with a subject, than possibily change some settings and use it on the same EEG-data. Is there a way to input the same EEG-File, that was alredy obtained in a previous session, in BCI2000 again?

Regards,
Timur

Timur,

Please check out the FAQ on the Replay question:

http://www.bci2000.org/wiki/index.php/User_FAQ

There is now a Fileplayback Source module (in V3/Contributions) that you could use. However, the comments on the FAQ still apply. For example, unless you choose the same random number seed (see page on wiki), the stimulus sequence will always be different.

Is the source code or executable for the FilePlayBack module still available? I can't seem to locate it on the BCI2000 SVN server.

Hello,
The FilePlayback module is located in the version 3 branch of BCI2000, and is located under src/contrib/SignalSource/FilePlayback. Please let us know i you have any other questions!
