Re: Skeleton-Generator doesn't want generate

Hi Siméon,

The folder should be in the openvibe directory which is create when you get the source code of OpenViBE.

About the generation, i will need the logs that are in the console that is launch when the generator start. Could you please copy/paste them.

Re: [Help] P300 Speller

You are right with the first point, but not with the second.
You don't need the stimulator in the second as you already have the sequence of stimulations stored in the CSV file. SO it's just
CSV reader (with output configured) -> p300 visualization

Re: [Help] P300 Speller

Hi,

You need to adapt the type of the input of the CSV writer. Double-click on the input and modify the type to Stimulation, and then connect.

Re: [Help] P300 Speller

Hi,

One simple way to avoid the randomness and have a fix sequence is to generate one sequence and to record it in a file (CSV or .ov) and to read this file instead of using the speller stimulator.

Re: Acquisition server with Emotiv headset on Linux

Looks like you applied the modifications in the wrong directory. You need to apply them in /home/simeon/Logiciels/openvibe-1.0.0/

Re: Acquisition server with Emotiv headset on Linux

Looks like we just fall back to error we've got friday. With all windows related issues. I took a second look to the first solution (the one from friday) we were try to set up. I think the problem comes from a mistake I made in the cmake file. So lets try with this solution and set it up to the end,...

Re: Acquisition server with Emotiv headset on Linux

Okay,
Definitely not the right version :).

Use that command to checkout openvibe.
git clone https://gforge.inria.fr/git/openvibe/openvibe.git

in your home directory
