Wout, there is a less strict consistency check in the latest CVS version of the BrainVisionAnalyzer converter tool, i.e. if you update your source tree and recompile the converter tool, it will not report the error any more. If recompiling is not an option, you might choose to modify the BCI2000 fil...

Hello Mark, thank you for your questions. The compilation errors you report should not occur with the code given in the current version of the Software Design Document, which is distributed along with the source code. The reason for the fatal error is difficult to guess without knowing your code in ...

Try using a relatively large timeout (e.g., a few seconds) to allow for detecting a broken serial connection. Ideally, your readSerial() function should block indefinitely while there is no data available -- thus, no CPU time will be used when there is no data processing taking place. If the large t...

BCI2000 comes with support for BrainVision systems. You should not have to do any coding.
The respective source module is called "RDAClient". RDA stands for "Remote Data Access" -- this is the name the BrainVision developers gave to their real-time data interface.

Best,
Juergen

Adam,

the behavior you describe is due to a bug that slipped unnoticed for some time because many of us don't use the SubjectRun parameter in their data analysis procedures.

I fixed the bug, so the current CVS version should behave as you expect.
Thank you for reporting it!

Regards,
Juergen

Dear Jean-François, granting access to academical/institutional research only is a general policy of the Wadsworth Center which hosts the BCI2000 project. There is nothing we can do about it, nor can we give any further reasons or explanations. The workaround to this is to get some support from an a...

Re: States

Paul,

the header of a BCI2000 .dat file is human readable.

When observing "strange" things, use a text editor (or "more myfile.dat" from the command line) to tell what states and parameters are contained in a given dat file.

CVS access

Febo, you are trying to use the "bciro" read-only account to access the CVS server using a CVS client program on your machine. For read-only access, there is the cvsview web interface at http://turtle.medpsych.uni-tuebingen.de/bcicvs , as described in section 4 of the CVS setup document. For read-on...

Hi Brendan, to the right of each channel number, there is a tick mark which has the same color as the channel's signal. The idea is to provide the user with the association between channels and colors, while at the same time keeping the numbers readable even for dark colors. The colors are also user...

Dear Febo, the source code from Feb 13 is quite likely to be the same that is contained in the May 20 executable. Of course, if it is the version from the installation program, you need not send it to me. Have you tried the RDAClient.exe version I sent you per e-mail about a week ago? It should give...

Dear Febo,

using the Workspace and *.prm file you sent me, I could not reproduce the problem here. Could you possibly send me the executables of all four BCI2000 modules that you are using?

Febo, in the Recorder software, there is an option that allows you to switch between a "demo" input (sine waves with a frequency proportional to channel number) and the true A/D input. To me, the values mentioned in the error message (8 Ch, 100 Hz Sampling rate, 1000 nV/AD unit) look like the ones s...

Are you re-starting or re-configuring the BrainAmp Recorder software between runs? Could it happen that you have two instances of the BrainAmp Recorder software running?
