SSVEP : Cannot change size or place of Flickering Boxes

Post by mashah1220 »

Hey.

I am trying to interface an EMOTIV EPOC Headset with OpenVibe for the Analysis of SSVEP Signals. I need to create two flickering boxes with frequencies in the range of 7.5-20 Hz. I have ran the "ssvep-bci-0-acquisition-test" and "ssvep-bci-1-ssvep-configuration" files. They run fine. However, I am unable to change the number of flickering boxes, their size or their position in the simulation by changing the parameters in the "SSVEP Training Controller" Box in the "ssvep-bci-2-training-acquisition" file.

Please help !! :(

Thank you.

Regards,
MAS.

Hi,
I know this is a late reply. But, I guess it might help someone who is facing a similar issue...
Even I was facing a similar problem, so recently figured out a solution to this.

So you can change the size and the position of the boxes by modifying the values in the config file that can be found here:
C:\openvibe\share\openvibe\applications\ssvep-demo\trainer.conf

You can use any editor like notepad++ to modify and save the file. Then run the ssvep trainer scenario.
