Depending on your needs, the simplest solution is to use the AppConnector interface. The app connector sends the processed data to a UDP internet port, which can then be read by any application WITHOUT the need for the BCI2000 framework. There are some examples in the BCI2000/src/contrib/AppConnecto...

Hello, Just to follow up on your question about C#, there are no plans to port BCI2000 to C#. However, a similar project has already be accomplished using Python, so something similar using C# should be possible, if you want to take that on :-). Alternatively, since BCI2000 modules communicate using...

David,
Do you get a compilation error right now, or is the behavior of BCI2000 different from what you would expect?

Sorry for leaving this unanswered for so long. Can you let us know which filters are giving you the problem? There is a very simple fix for this, but we should add it to the distribution so that others don't have this problem. Also, have you recently updated BCI2000 through SVN? Some of these proble...

Hello, This is actually something that I have already done. It adds the ability to individually save each step of the processing chain in a simple binary format (NOT the BCI2000 dat file format). If you are interested, send me an email at adam.wilson@uc.edu, and I can give you instructions for compi...

Hello, One of the biggest problems with first-time users is making sure that you have a good connection between the electrode and scalp. You should make sure that you sufficiently abrade the scalp and apply enough gel. Does your amplifier have an impedance check function? If so, the impedance for al...

Hello, This is certainly something that could be done with a little work. I modified the P300 speller to send messages to Twitter, and the same concept would work here. What you need to do is figure out the transport system you will use to send the messages. For example, it is possible to send text ...

Hello, In response to your long email, here is a short one :-): Can you somehow send me one or more of your data files, so that I can look at them quickly to see if I catch anything? Do you have an FTP site you can give me access to, and put them there? Something like: http://www.yousendit.com/ woul...

Probably the best way to do this is to use some type of stimulus detection hardware, such as: http://www.gtec.at/products/g.TRIGbox/gtrigbox.htm http://www.cedrus.com/stimtracker/specs.htm The first is made by g.tec, and sells for ~$3600. The second is made by Cedrus, and sells for ~$800. Alternativ...

Now, I am thinking about developing my own program using only BCI 2000 to revise original BCI 2000 source codes, not using g.tec one. In that case, is it possible to use visual studio as well as matlab? Also, what kind of differences are there between BCI 2000 and g.tec software when I develop my o...

The g.mobilab+ is fully supported with BCI2000, and you do not need any other software to acquire data with it. For developing your own program, do you mean you want to write a program outside of BCI2000 that uses the g.mobilab? If so, you will need to contact g.tec directly to get access to their C...

Hello,
Using Google, this error appears to be caused by outdated Intel graphics drivers. Is this what you are using, or do you have an NVIDIA/ATI graphics card? If you have Intel graphics, update the drivers, which will allow it to support OpenGL. Let us know if this works for you.

Thank you for reporting this. The spatial filter matrix was essentially transposed in software, which resulted in the behavior you saw. Update to the latest SVN, and it is fixed there.
Sorry for the bug!

Ahh, yeah. Just set the Adaptation parameter to 0 0 0, and it should work.
