Re: including resting data with recording

Hi, BCI2000 will record data for all values of TargetCode, it is not possible to restrict recording to certain values of that. If you feel you are missing data, you may have got the SamplingRate wrong when considering the number of samples? Apart from that, I have difficulties understanding what you...

Re: Problem with P300 Speller Task with Emotiv Flex

In the meantime, I found out that there is an error in the batch file. In P3Speller_LSLSource.bat, replace "DummySignalProcessing" with "P3SignalProcessing".

Re: P300 calibration - text not advancing

There is an error in the batch file. Replace "DummySignalProcessing" with "P3SignalProcessing", and it should work.

Re: Problem with P300 Speller Task with Emotiv Flex

Re: Problem with P300 Speller Task with Emotiv Flex

There are multiple possibilities why this may happen. 1) The NumberOfSequences parameter is set to a different value than EpochsToAverage parameter. 2) You have specified the <PAUSE> command for a letter contained in your text. For more information about the P3SpellerTask, see https://www.bci2000.or...

Re: Include Laplacian in Offline Analysis

Hi, the OfflineAnalysis tool actually includes a spatial filter, the optional Common Average Filter (CAR Filter). This is implemented in the carFilt.m file.

Make sure that any CPU intensive initialization is done during your application's Initialize() function ra...
