Thanks for the information.
We are currently working on a new BCI2000 installer.

This is a Matlab exception that indicates that no memory could be allocated for the signal data in your file. Within Matlab, a file requires a little bit more memory than its size on disk. With a 32 bit version of Matlab, the maximum file size that load_bcidat() can read is about 1.5GB. You may get ...

This is due to an error in P300Speller that was fixed in r6166. I'm sorry that you experienced this issue. We generally recommend to build BCI2000 from the latest SVN version as described here: https://www.bci2000.org/mediawiki/index.php/Programming_Howto:Building_and_Customizing_BCI2000 If you woul...

Hi,

the BCI2000 GUI is not a library. If you want to write your own GUI on top of BCI2000, I suggest you start out with the Operator (OperatorQt) and modify it by adding or removing elements as you see fit.

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...

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

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

Hi, can you post the contents of the batch file you are using?

Hi, for an introduction how to use BCI2000 (and how to locate and modify parameters), please see this wiki page: https://www.bci2000.org/mediawiki/index.php/User_Tutorial:BCI2000_Tour The EpochsToAverage parameter is on the "Filtering" tab. It is strange that the P300 Classifier program do...
