I'm writing a Python script for a Python Script box. How can I send stimulations to the acquisition server box?

I'd like to mimic some of the performance of the P300 speller. Looking at the implementation in openvibe-1.3.0-src/plugins/processing/simple-visualisation/src/box-algorithms/ovpCBoxAlgorithmP300SpellerVisualisation.cpp, it appears to me that I need to send OVTK_StimulationId_NonTarget and OVTK_StimulationId_Target stimulations.

Can anyone indicate a document or share instructions telling me how to accomplish this through the Python interface?

Hello Entrity, there's a python example of that in the openvibe source tree,

https://gitlab.inria.fr/openvibe/extras ... -client.py

maybe that helps? Some more detail can be found here,

You can use stimulation listener box after the acquisition client to get a more clear idea of the kind of timeline the visualizer sends. The target/nontarget indicate if the flash is the one the user should attend to, or not (given the letter to be spelled).

Thanks, Jussi. Seeing those examples was very helpful.

(I see that I had better try another strategy, however. I want the feedback that the P300 Speller Visualisation gives, such as showing what the latest prediction was, and I don't think I can figure out how to replicate the algorithm before my deadline. I'll start a new thread.)
