OpenVibe: motor-imagery-bci-2-classifier [resolved]

I use OpenBCI with 8 channels (O1; O2; P7; P8; C3; C4; FP1; FP2) and 2 SRB & Bias earclips on the Board.

I ran the motor-imagery-bci-1-acquisition and created the .ov file with OpenVibe framework.

I try to run the motor-imagery-bci-2-classifier-trainer but I get an error

As a Reference Channel what should I put?

In the Surface Laplacian Box -> Spatial Filter coefficients there is this (4; 0; -1; 0; -1; -1; 0; 0; -1; 0; 0; 4; 0; -1; 0; 0; -1; -1; 0; -1)
What does it mean? Please explain to me ..

I have put
Number of output channels = 2
Number of output channels = 8

What do I do wrong and get errors? (see attachment image)

Thanks for any help!
