Use of OpenVibe Stimulations for epoching

Post by openvibeexplorer »

Hello there,

As far as I know, P300-Speller scenario uses "OVTK_StimulationId_Target" and "OVTK_StimulationId_NonTarget" stimulations during its "training" mode for epoching. P300-Speller also uses "OVTK_StimulationId_VisualStimulationStart" during its "online" mode for epoching.

Question 1 - Shouldn't we use same stimulations for "training" and "online" mode for epoching, to get correct classification and prediction results?

Question 2 - Could you please help me know functional differences among below set of stimulations - if any

1. OVTK_StimulationId_Target and OVTK_StimulationId_NonTarget
2. OVTK_StimulationId_VisualStimulationStart
3. OVTK_StimulationId_Label_01 // 33025
OVTK_StimulationId_Label_02 // 33026
OVTK_StimulationId_Label_03 // 33027
OVTK_StimulationId_Label_04 // 33028
OVTK_StimulationId_Label_05 // 33029
OVTK_StimulationId_Label_06 // 33030
OVTK_StimulationId_Label_07 // 33031
OVTK_StimulationId_Label_08 // 33032
OVTK_StimulationId_Label_09 // 33033
OVTK_StimulationId_Label_0A // 33034
OVTK_StimulationId_Label_0B // 33035
OVTK_StimulationId_Label_0C // 33036
