Hi,

I am newbie in Openvibe. I want to do a realtime data processing via Openvibe. I have trigger which is sound and I want the EEG to be segmented based on this trigger.

Here, I have two questions.

1. Is it possible in Openvibe to segment the EEG signal based on trigger? This trigger is an external

trigger box which I connect to the laptop. I already try to display the EEG signal and trigger using
the signal display box and it works.

2. I also try using the Matlab to save the EEG signal. However, I cannot save the data as the data

keeps overwrites and only save the last data. So, is it the EEG data collected actually able to be
saved in Matlab or the EEG data only can be saved using the box available in Openvibe?

Thanks.

I didn't find the right solution from the internet.
