I changed the input type of OSC controller to streamed matrix and it worked.

Hello Thomas,

This helps a lot!! Thank you for your response and clear explanation.

Best wishes,

If I am computing alpha power which is around 10Hz, then I could apply multiple oscillations to estimate its power, for example, 300, 500, and 1000ms window, right? Now my question is, in this case, do I need to use different time based epoching boxes, or should I write these times in epoch interval...

Hello Thibaut, Thank you so much for your reply. I will use the time based epoching! So in my case, it is enough to firstly channel selector, then temporal filter, then time based epoching and then send the data to osc controller? In case to compute alpha amplitude envelope, what epoch duration and ...

hello, I kindly want to ask you help me understand how I can compute alpha amplitude envelope (square root of the power) over 250 samples every second in OpenVibe? Can I do that with sliding window, e.g. every 100ms compute it over the last 250 sample? I read somewhere in the forum that I could use ...

Thank you Thibaut for your answer. However, notch filter is meant to remove the interference of the mains or electrical power supply that leak through everywhere... So I figured that in my country it is 50Hz, 220V. I understand what you say but the makers of the EEG device recommends to use both not...

Hello, I wanted to ask something regarding data filtering. I use Unicorn EEG device from g.tec and I am sending the data through LSL to OpenVibe. I send the data out from OpenVibe as OSC message to the network and receive it with another program in order to program sound. https://i.imgur.com/Bk5ZgX5...
