Eye Blink Identify

Post by harithhansaka »

Hello everyone,
I want to detect eye blinks. for that, I've modified mi-csp-2-train-CSP.xml, one epoch as OVTK_GDF_Eye_Blink. What is the other epoch type, which is for identifying the non-blink?

Thank you

Hi Harith,

In the file you stream, there is the OVTK_GDF_Eye_Blink stimulation to indicate an eye blink, but is there another stimulation to indicate windows of non blink ?

At the moment there is no box that would epoch continuously unless a stimulation is received (e.g. Eye_Blink), so you could use a different stimulation to indicate non eye blink windows for epoching. This would be the closest approach to the original right/left arm.

Otherwise, if you don't want to add aNon_Blink stim in your recordings, you could work with a python box to output Non_Blink stims at regular intervals (sent to the non-blink stimBasedRpoching box on the right of the scenario) and pause whenever an Eye_Blink stim is received.

Hope this helps. Don't hesitate to ask for clarification if what I wrote is not quite clear.

Cheers,
Thomas
