Jesus, the error message you are getting indicates that you are defining PlatEEGADCSyncTriggers as a STATE, but accessing it on a sample by sample basis. For this purpose there is a STREAM definition (see below). Please try to change your state from STATE to STREAM, this should fix the issue. On ano...

Jane,

can you please past the output of your compiler as well as the listing of the BCI2000/prog directory. I will check to see if I can determine from that what is missing.

Regards, Peter

Joycejin, without debugging this will be difficult to resolve. The module was initially developed by Griffin Milsalp for the Neurosky MindSet. Can you pelase check that you have this device and also which version of the ThinkGear DLL is installed on your machine. You should have a line in your opera...

JaneATY, the errors you are getting in building the NicoletOne binary are expected, as this requires MFC support, which is only included in the professional version of Visual Studio. However, the remaining BCI2000 binaries should be build. To isolate the issue you please past the entire build log an...

lsegura003, The issue in your code is that the str2double function expects a number in the bci_Parameters.SamplingRate variable, e.g., '120', but in reality this variable has the unit 'Hz' attached, i.e., '120Hz'. To overcome this issue use, 'sscanf(bci_Parameters.SamplingRate,'%i')' in your code. A...

Lsegura003, the in_signal matrix is of size channels x elements, where the number of elements depends on your SampleBlockSize parameter. Which channels are transmitted to your MatlabFilter depends on the TransmitChList parmeter in the Source. For example, you could record channels 1 to 16 but also t...

Joycejin, the error message can result from either the baud rate the COM port number being set incorrectly (see below). Can you please verify that you Neurosky device is connected to the COM port set in the corresponding BCI2000 parameter? // Attempt to connect the connection ID handle to serial por...

JaneATY, I would suggst the following steps: (1) Check out BCI2000 SVN trunk [1] to a new directory without using space in the path. (2) Run the "Make VS2012 Project Files.cmd" command to build a 32-bit version of BCI2000 (The Emotiv source is only availible for 32-bit). Make sure you select the pro...

D5006ehr, you have two options to acquire data from Neuroscan devices in BCI2000 and to process them in real-time using MATLAB code. (1) Using the NeuroscanADC.exe as the source module [1] and the MatlabSignalProcessing.exe as the signal processing module [2]. This requires that you have the Scan 4....

JaneATY,

can you please confirm that you did a "Build All" in Visual Studio? This should build the executables listed above. Let me know.

Regards, Peter

Joycejin,

you wil need to use the 32-bit version of BCI2000, as there is no 32-bit version of the thinkgear.dll.

Let me know if this resolves the issues.

Regards, Peter

Minguillon,

you are welcome and I am glad that this is now working for you.

Regards, Peter

David, thanks for the extensive testing. I might have to ask you to help me with further isolating the issue. For this I might ask you let me debug the issue on your machine using a TeamViewer remote session. Let me know if that would be possible for you. In the meantime, I can offer you a workaroun...

Minguillon, I suspect that the loading of your API functions from the DLL does not properly work. I see that you are using the last release (i.e., v3.0.5). Can you try to download the latest trunk source code [1]? To build this, follow the instructions in the BCI2000 v3.6 beta test thread [2]. Once ...
