motor imaginary CSP online 4. xml crashes
The three previous stages worked well. Finally when I try this online experiment, it would crash and quit quickly after the clicking of start. I could only see the error in the console problem.PNG . The problem is that I never have a user name appearing in this figure, do not know where it comes fro...

problems about CSP Spatial Filter Trianer BOX
Hello, I have some problem about the CSP Spatial Filter Trianer BOX. I use it on our own data in OpenViBE, which is really convenient, and get a configuration XML finally. The spatial filter coeffcients results we get are like this (after reshape it)↓: https://pcsdata.baidu.com/thumbnail/bdb36313bm9...

Re: problem with stimulation codes using run command
Hi again, I guess is it something about serial port ? I read about the tutorial Overview: Sending data & stimulations to/from OpenViBE (http://openvibe.inria.fr/overview-sending-data-stimulations-out-from-openvibe/),and it seems that Do-It-Yourself is not currently supported, right? It is sometimes ...

Re: problem with stimulation codes using run command
Hi, Thanks very much for your answer. Sorry for forgetting to list details when asking. Let me hastily add, ChannelOne.exe is switch of the electrical relay(when launching it, electrical relay starts to give out electrical stimulation). R is a random value using to just find out OVTK_GDF_Feedback_Di...

problem with stimulation codes using run command
Hi, I’m trying to start our electrical stimulation during a MI trial by using the run command box . However we experience some problems with the configure setting. Our plan is that after the cue shows and the EEG is classified as the correct hand side of motor imagery , the electrical stimulation se...

Re: higher baudrate does not work
Sorry, I found it was my mistake.
There were three places, I only changed two.
Now 256000 is working and it seems all 16 channels have same signal quality.

higher baudrate does not work
Hi, here I am again , with a new problem. We have adapted the driver of modularEEG to our device, and the original baud rate is 57600. When we increased it to 115200, everything was OK, however, when we made it 256000, it does not work anymore. It just do not receive data with "[WARNING] After 5000 ...

Re: error building python box
Hi, Thanks for your answer! I checked my work again and I was sure I had added the path but the problem still remained :cry: . Then I thought it might because I had installed several python so that OpenViBE couldn’t find the right python installation.(my guess is according to lines in the tutorial ↓...

I am trying to use an ensemble classifier(e.g. lda+mlp) in the motor-imagery-CSP example. And I would like to use python scripting box to help me realize it, but I'v got some problem when using that box. 1. I just cannot find the python scripting box in the Scripting folder. And the scenario Python3...

Re: tagging does not work with our equipment
Thx, I got it. One thing I want to say is that I did a little modification to the stimulation also. But found out when configure sound player settings, the PLAY trigger should be OVTK_GDF_right or OVTK_GDF_left. Yet in the stimulation list it is OVTK_GDF_Right or OVTK_GDF_Left. Maybe someone else wo...

Re: tagging does not work with our equipment
Thanks for your reply. We also found out these tagging do not interfere with motor imagery tagging. However, I still wonder where do these tagging come from? We used the driver OpenEEGModularEEG, and did not modify it. If you could tell me which lines are for these tagging I will be very appreciated...

Re: tagging does not work with our equipment
I found the stimuli list. OVTK_StimulationId_AddedSamplesBegin OVTK_StimulationId_AddedSamplesBegin 0x00008311 OVTK_StimulationId_AddedSamplesEnd OVTK_StimulationId_AddedSamplesEnd 0x00008312 It seems we are receiving these stimuli repeatedly, almost 25 Hz, when doing acquisition. Could anyone possi...
