Bonjour,
Je suis un utilisateur non-expérimenté sur openvibe.
J'aurais quelques questions par rapport au scénario "motor-imagery-bci-3-online.xml".
En effet, lorsque je lance le scénario l'écran reste noir (Graz visualisation).
Est ce normal? Ai-je oublié une étape?
Merci

Re: Questions on the motor-imagery-bci-online
Dear yannick,
thank you for your interest in our software and welcome on this forum. For your information, this forum is english for larger audience. I hope this is not a problem for you and that you'll be able to reply in english.
Concerning the problem you are talking about (Graz visualisation keeps being black when using the motor-imagery-bci-3-online.xml scenario), I guess you didn't run the scenario over the 40 first seconds. The 40 first seconds can be used for "baseline" computation. They reflect a "no specific mental task" state of the BCI user. Passed this 40 seconds, you'll have the stimulations.
Keep us posted if you still have problems.
Hope it helps,
Yann

Re: Questions sur le motor-imagery-bci-online
I have a question about the connection with openvibe.
In fact, i used motor-imagery-bci-3-online.xml and i want to know how connect the output of this scenario with a other software or a file.
For example, if i want to write in a text file "right" or "left" in relation to the user's hand movements:
If he move right hand --> "right" will be write in the text file do you understand me?
Instead of use Graz visualisation i want to write in a text file, it's possible?

Dear yannick,
there are several ways you can achieve such behavior.
The most straight forward is to put a stimulation listener box just after the classifier processor. It will print in the log file each classification. You will have to do a bit of analysis to the printed line to extract the actual stimulation name, but I guess a couple of regexp will do it !
Another method would be to use the run command to run whatever external command you want based on the output of the classifier processor. You could try something like
Tell me if you need more assistance on this.
Hope this helps,

Code: Select all
echo "WhateverClass" >> whatever-file.txt
