Thanks Jozef for your reply! I have shifted to xDawn version of the P300. It's easier to deal with and clearer. Now I am done with signal monitoring, acquisition , xDawn training , classifier training SUCCESSFULLY! :) But the online mode is not working properly. What I did in this scenario: 1.Discon...

Thanks for the reply Jozef! 1. What about the second error of not abling to open the file? [WARNING] At time 0.000 sec <Box algorithm::Generic stream writer> Could not open file [record-[2013.02.25-01.03.40].ov] I guess I'm writing something wrong in the "File name" option of the Generic Reader/Writ...

I am wondering too about the generic stream writer. Regarding the name of the file that we have to specify, will the generic stream writer create a file of type .ov by itself named by the specified name? I'm getting this error: [WARNING] At time 0.000 sec <Box algorithm::Generic stream writer> Compr...

Maybe you have to just connect the signal output of the acquisition client [that is already available] to the identity, without removing the generic reader since it's providing the stimulation.

Hi everyone I'm willing to use OpenViBe to implement P300 speller using the available 3 scenarios[acquisition - train classifier - online]. I want to add extra processing techniques (USING MATLAB SCRIPTING BOX) like: -Pre-processing : PCA - ICA -Feature Extraction: Wavelet - Peak and area calculatio...

Hi everyone, Sorry if I bothered you with my posts, but I am very new to openvibe :) My trivial question is: I want to take a signal, say from the generic oscillator, and using the matlab scripting box, I want to take the signal, muliply it by -1, and add to itself and finaly send it to the signal d...

I switched to a computer that has win32 .. problem solved

Where can I find win32-dependencies.cmd ?

I am facing the same problem actually !

I have windows 7 on my 64-bit laptop.

I have MATLAB R2009b , 32 bit.

Hi,

I am trying to check if matlab is working fine with openvibe on my laptop. I am trying to run "tutorial 2".

I followed the steps but it seems there is something wrong.

Hi everyone,

I am having a problem using matlab in openvibe. I followed the steps mentioned in the tutorial but still getting an error.

For example, when trying to implement tutorial 2, this is what I get.

What do you think??

Hi everyone ,, I was wondering if I can use the (Stimulation based epoching) box in a P300-speller scenario. Is it possible to make the ( Input stimulations) the flashing of a row or a column in the P300 matrix? If yes how is that? I guess I'll need then 12 (Stimulation based epoching), each is for ...
