EEG data in edf format missing event information in EEGLAB
Hi everyone, I am exploring the motor-imagery scenario using ANT EEGO device. Currently, it is working okay, the online accuracy for most subjects is bigger than chance level. But I am encountering a problem when doing the data analysis with EEGLAB. To be specific, the EEG data can be read from Open...

EEG channel mapping of EEGO in OpenViBE 2.0.1
Hello all, I am trying to run motor imagery scenario with EEGO in OpenViBE 2.0.1. 90 channels, including 64 + 24 + 2 (EEG + BIP + STATUS), can be acquired from EEGO. The issue is I cannot find the exact mapping of the 64 EEG channels. To be specific, I only need channels (AF3;AF4;F7;F3;F4;F8;FC5;FC6...

Re: Problems using TCP writer to send data from OpenViBE
Thank you very much for your help. We finally connected OpenViBE to Python and got the data we need.
Have a nice holiday.
Best,

Problems using TCP writer to send data from OpenViBE
Hi everyone. Recently I have been trying to send data from OpenViBE to Python by adding a TCP writer in the program. The data I want to send is the classification results in motor imagery with csp, receiving online EEG data from EMOTIV EPOC. When I try to connect the python server with the TCP write...

Re: Poor performance on motorimagery and P300speller with Em
Hi Jussi, Thank you for your fast response and good advice. This time I included 8 nodes in motor-imagery-csp. They are AF3, AF4, F3, F4, F7, F7, FC5, FC6 on emotiv, but again I tilted it so two nodes cover C3 and C4, with the others around them. I have to say the cross-validation accuracy is surpri...

Re: Poor performance on motorimagery and P300speller with Em
Thank you for your replies. It has been a long time. I have a master student who is working on this, but the progress is still frustrating. The emotiv panel shows the impedances are okay, and in the signal-monitoring program, eye blinks and jaw clenching are visible. I tried both motor-imagery and m...

Poor performance on motorimagery and P300speller with Emotiv
Hi everyone This is my first post in this forum. I just started to use Openvibe to build BCI using Emotiv EPOC+ . Having read related posts in this forum, I chose the scenario with CSP to run motor imagery. Since Emotiv cannot cover C3 and C4, during the testing, I have the headset tilted. In the fi...
