Hello everyone!
I'm very new to this field, and I'm willing to do BCI based project as my final year project.
I'm using g.Tec HIamp amplifier and use 10 input channel which are (C3;C4;FC3;FC4;C5;C1;C2;C6;CP3;CP4), Nz use as reference channel.
But I got this error message. When I remove the "Reference Channel" box, same result but with C3 which was the first input channel.

Can anyone can help me to get over this problem. Thank you very much. (https://ibb.co/Sx3yvxh)

Hi,

The error message you see means that the Reference Channel box tries to use the channel Nz as reference, but there is no such channel in the incoming signal.

This is because, out of the Acquisition Client box, your channels may be named with simple numbers (e.g. Channel 1, Channel 2, Channel 3...).
You can put a Signal Display box right out of the Acquisition Client, in order to display the channels, and therefore see their names. You will find that there is no Nz channel indeed.

You can modify the names of channels to get more meaningful names with the box Channel Rename.
If you put it just after the Acquisition Client, the scenario should work fine without any other changes.

Hope this helps.

Cheers,
Thomas
