yes, it is a linking issue. I switched to visual studio. I do know I'm adding the library correctly since as a test I added the SDL library using their tutorial in here http://www.willusher.io/sdl2%20tutorials/2013/08/15/lesson-0-visual-studio and it was successful. But when I repeat the same proced...

I 'm trying to connect openvibe to a c++ program using a VRPN server. in the corresponding tutorial, it says I should run a script to get the header files which I did. I also added the headers to my project. the problem is when compiling the same code provided in the tutorial I get the error : undef...

In my scenario, I give the simple DSP box two inputs. In the first case where the box is called “average T7 and T8_Simple DSP” I know the two inputs are synchronized since the parallel threads are doing the same thing. But in the second one where I’m calculating “theta_power/total_power” I know that...

assuming that the input to the simple DSP box is a matrix X and we write the expression X*X as the Equation.

does the * operation in the simple DSP box mean matrix multiplication or is it an element-wise multiplication?

thanks for the reply.

1. as you said I should manually change the address to the new file created each time.

2. I was not paying attention that in OV addresses are separated with '/' instead of the Windows default '\'!

thanks for your reply.

indeed the matlab box worked just fine to make a simple game. and I would highly recommend reading it's tutorial in http://openvibe.inria.fr/tutorial-using ... -openvibe/ and the problems I faced in viewtopic.php?f=13&t=9789 .

thanks for the reply with a friend's help I managed to solve the problem. 1. as you stated above the addresses used in OV should use '/' instead of '\' which is the default way of separating an address in windows (I really don't get the reason behind that; because it can potentially cause a lot of u...

hi , I'm trying to make the matlab box work to show me a graphic interface.I have windows 10 64bit / matlab 2011a 32 bit 1. my matlab.exe path is "A:/Program Files (x86)/MATLAB/R2011a/bin/matlab.exe" and I set "Path to Matlab executables " in the properties of the box to it . 2. my function is in th...

so I'm currently working with the Bci-motor-imagery example provided with openvibe . I want to add a simple game to it . for example the user should move a box by thinking about right or left and earn points. so what is the easiest way to design a simple game like that? currently, I'm thinking about...

would you provide a reference to these types of trainings?

I was running the mi_csp scenario when i got the error ".... CSP Spatial Filter> Bad matrix size _ Filter has 11 channels but data needs 16 channels" I 'am using emotiv epoch+ and I think I know where the problem arises. in the scenario mi-csp-1-acquisition . using signal display I figured out the "...

I want to know if this is how the time epoch box works in the spaceship scenario . and I have 2 questions : 1 . how does the time epoching work in conjunction with the average box ? after bandpassing the input stream we have a time epoching box which I think works like this (assuming we epoch durati...
