Re: Replay pre-recorded cursor position data with BCI2000

Hello Peter, Thanks for your reply and support. I am working with BCI2000 (3.0.5). I could save the data and velocities into a new file (by using save_bcidat). Right now, I have the ExpressionFilter, but I am not sure how to tell BCI2000 to read my saved file. ExpressionFilter has three options: Sta...

Replay pre-recorded cursor position data with BCI2000

Hello All, I have a pre-recorded cursor position data file (X,Y). The data was recorded from a cursor control task for some minutes. I wonder how can I reload/replay this file by BCI2000 to be able to control the cursor position/velocity in cursor task application? For training phase for the subject...

Reading BCI2000 data by MATLAB and throguh UDP port

Hello all, I am testing BCI2000 for UDP connection for my future application. I ran BCI2000 with SignalGenerator, ARSignalProcessing, and CursorTask modules. Then, by using AppConnector help, and binding UDP ports in a MATLAB script by a code that I found online as follows: -------------------------...

Re: CursorTask & MATLAB & DummySignalProcessing

Hi Peter, In my experiment (training session), I want to control the cursor (velocity/position) by input control signals from mouse (position). I was validating the velocity calculated by: v_0 = (screen width)/(2*FeedbackDuration) v = v_0 * (control signal) = (control signal) * (screen width) / ( 2*...

Re: CursorTask & MATLAB & DummySignalProcessing

Hi Chad, I am using the latest version of BCI2000 (3.0.5) and the latest stable source code, as well. Both core CursorTask module and the compiled one (by using the source code) have this problem. I double-checked and the problem is still there. I think it should be a bug. I did not try to employ th...

Re: CursorTask & MATLAB & DummySignalProcessing

Hi Chad, Thanks for your help. About velocities of the cursor and distance traveled by the cursor, I did several tests and finally I think I figured out the issue. It seems to me there is no problem with the velocity formulation. My understanding is that this formulation is based on a screen width w...

Re: CursorTask & MATLAB & DummySignalProcessing

Sorry for this delay. If I am right, your name is Chad. Thanks a lot for your help. About your help for question 5: I checked the software again. I am not sure where can I change the parameter so that hitting the target does not finish the trial. Can you explain a little more, please. About question...

CursorTask & MATLAB & DummySignalProcessing

Dear All, Concerning real time cursor control task, I have some questions: 1- First of all, I want to be sure that the input control signals to the CursorTask application are the cursor velocities. I am using MatlabSignalProcessing to control the cursor. I want to be sure that the generated output s...

Re: Roundtrip time Error

I switched the RenderingQuality setting to low (0)! It worked on two PCs which I had this problem with. Thank you very much! But I think for future demonstration, choosing this low quality is not a good option. I was wondering if you had any suggestion to have a high quality as well. Is it a good id...

Re: Roundtrip time Error

Thanks for your reply, I have just changed the operator on my PC to Windows 8 similar to my laptop. But, anyway, it still does not work even with setting the source to not write the file. The CursorTask is running at around 14%,15% of CPU during operation on my PC and I am getting the error. I think...

Roundtrip time Error

Dear all, I was running BCI2000 (3.0.5) and "cursortask_signalgenerator.bat" on our lab PC (with Windows 7 Enterprise) and after clicking on start button, I got the error: " DataIOFilter::Process: Roundtrip time consistently exceeds block duration". Meanwhile, I did not receive this error when I use...
