Information related to stimuli in gfd file - SSVEP scenario

Post by lezan »

Hi guys.
First of all, thanks to developers for your work and for what you continue to do.
I wanted to ask some information about reading and writing gdf files through OpenVibe. I tried the scenario on the SSVEP. In particular, I have added to the scenario SSVEP-bci-2-training-acquisition.xml a gdf writer. Then I went to read the file generated with SigViewer first, and then with a small scenario of openvibe, but never get information related to stimuli that occurred during the training phase. Have you any suggestions?

Modding of SSVEP-bci-2-training-acquisition.xml scenario. Only an GDF writer added.

Thanks in advance for your reply.

No one have some input to give me?

Thanks guys!

EDIT:
Okei, I solved the problem, in fact
OVTK_StimulationId_Label_00 = 0x00008100
OVTK_StimulationId_Label_01 = 0x00008101
OVTK_StimulationId_Label_02 = 0x00008102
OVTK_StimulationId_Label_03 = 0x00008103
OVTK_StimulationId_ExperimentStart = 0x00008001
OVTK_StimulationId_ExperimentStop = 0x00008002
OVTK_StimulationId_VisualStimulationStart = 0x0000800b
OVTK_StimulationId_VisualStimulationStop = 0x0000800c
