Biosemi cursor task and laplacian questions

I'm using a biosemi 128 electrode eeg, and I have two questions about implementation (one specific to biosemi, one a general signal processing question. When I run experiments, the online signal display usually only displays signal for around 4 channels, even though im collecting 128 channels worth ...

Mu Cursor Task Classifier

I'm a relatively new BCI user, and I'm trying to implement the Mu cursor task as described in the online tutorial. I'm a little fuzzy on some of the aspects of the classifier matrix: Input Channel: According to the tutorial we simply right C3_out, C4_out etc, but assuming we are using a slightly dif...

Re: Biosemi Active 2 source module

There are (at least) two versions of the labview_dll.dll floating around, make sure the file you are using is 48KB large. Email me if you still need the dll.

Re: BIOSEMI Source module

I want to give an update in case anyone else runs into this problem, as I think another user ran into a similar problem (http://72.249.19.64/phpbb/viewtopic.php?f=3&t=826&sid=e1ef8e1c599e6c15ab81e8bd9e59b5ec) First, in my earlier post I mistakenly refer to labview_dll.h, this is incorrect, the actua...

Re: BIOSEMI Source module

I just spoke to support at Biosemi, and the issue might be that the signal is not compatible with the new biosemi drivers. Does anyone know whether or not it was ever updated to handle the new drivers (also for the record Im working on an XP machine)?

Re: BIOSEMI Source module

Thank you for the reply. As I said, I have been able to use Actiview (version 605) to pull data from the biosemi hardware, however to be safe I updated the USB drivers to the latest version available off of the Biosemi webpage and the problem persists. Do the BCI 2000 files need to be in any special...

BIOSEMI Source module

I'm a new user, and I'm trying to use BCI 2000 to work with a Biosemi II EEG. As I don't have a great deal of C++ experience, I just downloaded the extended binary distribution, and since I wasn't sure as to whether or not it was still necessary, I also put Labview_dll.h in the BCI2000\prog director...
