PS: I tried it on the old version of OPENVIBE. (openvibe 1.2.0 & BIOSEMI MK2) I put 'stim based epoching' back to the original order(Like in the pic#1), and the result is that 1: Signal seems wrong( which works fine if I use OPENVIBE 2.2)(Like Pic#2) 2: Which let to an incorrect value (Like Pic#3) W...

Dear Thibaut Thank you for your reply. I fixed everything else but this one. Sorry for the lack of information before, here's my scenario and the problem is that I still can only gets the mean value and can't get the variance value.(like the pic that I uploaded) Therefore I can't get the threshold v...

I'm really new to BCI and I was learning neurofeedback by rebuilding spaceship-demo.

I'm using biosemi and instead of the demo file i tried to use acquisition client.

But not like the demo, when I open the spaceship app nothing changes.

What should I do.

Regards,

Felix

PS: If i use the demo loop (which is the stim based epoching before the Univariate Statistics) stim based epoching gives me the message: ERROR ] At time 1.625 sec <Box algorithm::(0x2b08ed95, 0x74b91d79) aka Stimulation based epoching> {Error description} : {Stimulation Based Epoching can not work o...

Dear Thibaut Thank you for your reply, Sorry for the late reply, Here what I made. If use the stim based epoching both mean and variance has no value.(Although might be the lua file befor I recreate the file I update the demo one and it only give the mean value without variance). So I tried time bas...

I wander if you fixed this cause I've been facing the same problem. Also I tried to put the stim based e[oching before the time base epoching, I can only get the mean, the variance is still X. Then I tried to build a new one inside using the stim base epoching, I used the time based epoching. Still ...

I'm the first one in my lab who want to try neurofeedback. In which I've been facing some problem and couldn't solve the problem by myself. I was trying to replay the'threshold_movement_calibration' and what happened was 1: mean and variance is always X 2:There's only mean and no variance 3:I tried ...
