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

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...

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: Micromed: Could not connect to operate module

Hi, BCI2000 consists of a set of 4 modules that need to run in order to make up a working system. To start up BCI2000, use a batch file from /batch, or use the BCI2000 Launcher from the /tools folder. It is strongly recommended to read and follow the "Getting Started" tutorial document in ...

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. In a first step, you may replace the call to carFilt() with a call to your own Laplacian filter function, and modify the GUI label to reflect t...

Re: Application warning:Execution required more than a sample block duration

It matters if it keeps repeating constantly. If it appears only intermittently, e.g. at start/resume, it is a hint that you should look at how your application module spends time in StartRun(). Make sure that any CPU intensive initialization is done during your application's Initialize() function ra...

Re: stimulus presentation image requirements

We have not noticed any special requirements for .bmp files. However, the top left pixel of a .bmp file is taken as the "transparent" color, so if you want to present monochrome images, you should put a frame around them. If you use the current version of BCI2000, it will be able to load i...

Re: parameter file and documentation

Hi, parameter files are not supposed to be edited by hand. The Operator module provides a config dialog for this purpose. If you prefer to edit parameter files by hand, the documentation you need is the one that describes the parameter format. It is available here: https://www.bci2000.org/mediawiki/...
