parm folder ...

Hi,

The parms folder is part of the BCI2000 installation that you get when you start the bci2000setup.exe file that is on the FTP server.

Hi,

The program you should use is BCI2000toASCII. It comes with the BCI2000 installation package.

NISource issue ...

Hey Sam, Please do keep me updated. It would be great if we could incorporate the updated version of NISource into BCI2000. It is interesting that I have never seen this problem before, though. I do know that the NIDAQ manual states something about a FIFO buffer. We've had some problems with DT boar...

P3Speller ...

Hi Janki, Do you mean a change in configuration or a change in the P3Speller code? You'll have to change the code of the P3Speller to 1) Present only one row 2) Determine the correctly predicted column and disregarding all rows SignalProcessing does not really know anything about the P3Speller. This...

P3Speller

Hi Janki, You can get information about the P3Speller from the BCI2000 User Manual (which is on bci2000.org -> Software Project -> Download), from the P300 Tutorial (on SourceSafe). Brendan should also know at least most of the necessary settings. There are obviously many parameters that have to be ...

P300 Speller Matrix data ...

Hi,

We have described the data format for the P3 speller matrix quite extensively for a recent BCI data competition. Please find it on http://ida.first.fraunhofer.de/projects ... sc_ii.html

I hope this helps. Let me know if you have more questions.

Some ideas ...

Hey Sam, I used the NISource with BCI2000 on a number of occasions - also quite recently. I could think of two more things: 1) You might have to manually set the referencing mode in NI's Measurement and Automation to 'Single Ended' as opposed to 'Bipolar.' Otherwise, you'll only have 8 instead of th...

P3Speller issues ...

Hi Jonki, What parameter file are you using? The application gets upset if, for example, it does not find the target definition file. Try install BCI2000 using bci2000setup.exe. When you then use this and load the parameter file that comes with it (in the parms directory), it should definitely work....

DAQ Issue

Hi Sam,

I've successfully used PCI-MIO-16-1 and PCI-6024E boards. In both cases, I used 16 channels. Have you tried using more than 4 channels? How many channels does the DAQcard support?

Signal values ...

The values that move the cursor are signal[0] and signal[1]. They are added to the current cursor position to produce the new cursor position. Thus, to the extent that I understand the problem correctly, if you transfer signal[0] and signal[1] to your application, you should be all set.

Control signals

Hi Umang, As described in my previous post, signal processing communicates an array of control signals to the user application. In general, it is completely up to the user application what to do with these values. In the RJB and D2Box task, for example, the first control signal moves the cursor up a...

BCI2000 control signal values ...

Hi, Signal processing passes a vector of control signals on to User Application. These values are, as you discovered, accessible to the application in the vector signals (i.e., signals[0], signals[1], etc.). At the same time, the nature of these signals depends on what signal processing module you u...

Adaptation ...

Hi, One component of system adaptation in BCI2000 is the intercept prediction. The offset that is subtracted from the (classified) signal is calculated as the average of the past Statistics->InterceptLength periods defined by Statistics->BaselineCfg. Thus, for example, if InterceptLength is set to 3...

You need to tell BCI2000 which board it has to get the data from. Each Data Translation board has a name that can be changed with the Open Layers Control Panel that comes with the board. This name has to match the BCI2000 parameter BoardName in Section Source. Per default, BCI2000 is set to use boar...
