Sending experiment information via VRPN

[fabien.lotte]

Is there a way in OpenViBE to send experiment informations (e.g., number of channels, channels names and locations, sampling rate, etc) to an external application using VRPN? Indeed, I may be wrong, but it seems that when sending signal matrices with a VRPN server in OpenViBE, only the actual signal is sent but not the matrix header which contains this info, is that right? If so, is there a way to send this info via VRPN?

Thank you in advance,
Fabien

Hello,

currently there is not a direct way of sending this information via VRPN. However it should be possible to "encode" this data by the Python scripting box.

Fabien,

just wanted to clarify one thing : the experiment information you are refering to actually are the matrix dimension(s) ; this information is in the streamed matrix datastream. The experiment information are embedded in a different datastream and include the subject age, gender, etc... You can learn more about the datastream structure in the dedicated page.

Hope this helps,
Best regards,
Yann
