Re: Biosemi-OpenVibe-Matlab Channel Structure and Sampling Rate

Hi, I can't help you. But for your compute time I have an advise : For me Matlab is not made for online processing. Python is a little better but if you wan't to make big process try to code a Box in C++. It's too hard if you never code in C++. But scripting langage are slower than other in general....

Re: Designer doesn`t start.

HI,
I can add : If you haven't this option. It's maybe because you have install python with anaconda or other all in one software, you must add to path python manually.

Re: P300 speller issues in replay scenario in version 3.0.0

HI,
If box are not white, there is a problem....
Red, is for box doesn't exist. I think you haven't run the good designer, it's in dist/extra not in dist/designer.

Re: filtering EEG data - notch filter

Hi,
If you have a band pass of 0.5-30, you have only frequency between this 2 values so filter of 60Hz is useless.^^
The noise can come from your setup (maybe electromagnetic, move, not enough gel....)

Re: OpenVibe P300 Speller Online - No "Green" box displayed

Hi,
If you build from source, with the git source, you can go to the development branch, normally the bug of P33 boxes are fixed. Tell me if not.

Re: With the 3.0.0, in P300 Online or Replay, the selected characters are not showed

Hi,
It's exactly the same scenario and dataset in input ? If yes, it's certainly a bug in new version. A lot of improvment were done and can break some stuff.

Re: Is there a way to change the Graz Visualisation blue feedback bar to be vertical?

HI,
The input value must be a success rate for each class so a probability not a distance hyperplane
