Hello, I tried to use the OpenVibe Acquisition Server, but I don´t know what number I need to put in the "Sample count per sent block". I read at site that this configuration is about the frequence. If I want use the 256Hz, what is the number that I need put in this blanck? Thank you soo much for yo...

Hello Dear,

In my project, I work with three stimulus classes. Because that, I need to add in the lua stimulator one more class, but I don't know how I do that.
Someone knows how I modified the box lua stimulator for add one more class?

Thank you

Hi, So, first, I used the scenario 'mi-scp-1-acquisition.xml' and I modified the Lua stimulator. The configuration file that I used in Lua Stimulator in attached. And where have the acquisition client I put the GDF writer which I put my signal file. Then, how I said I used the mi-csp-2-train-CSP.xml...

I understand now. Thank you, soo much.

Hi,

I don't know where I find the file that describes what the file OVTK_GDF_Right and the file OVTK_GDF_Right_Hand_Movement do exactly. I need this file for understand the difference between them.

Thanks

Hi Dear, I'm starting to use OpenVibe in few days just, because that my doubt can be ridiculus, if is sorry :) . I need to train a classifier. Because that I saw the tutorials and I found the file "mi-csp-2-train-csp.xml" this scenario computes Common Spatial Pattern to produce a spatial filter that...

Urgent!! I need to trainer my classificator. For this I have a Signal that I have getten with EEG and this signal is about the right hand and left hand movement. I want to use the power spectrum analysis to pick the features and trainer my classificator. I did that I discribed, but the classificator...

Hello, I have a signal that I did the Fast Fourier Transform with OpenVibe, and I need pick this FFT signal to trainer my classificator. But, I don't know what the box I need to use. Then that I want pass this signal in a classificator and it return me for example if the signal is about the right ha...

Hello,

I have a signal obtained with a g.tec product that is in a matlab program and it is in a .mat format. I want to use this signal in Openvibe, because this I need to read it. Can I read the signal using GDF reader? If I can, What's the format that I need to convert my file .mat?
