Hi there,

I need some labels to understand the colors red,blue,purple, green yellow
that shows up in the 2d map
what do they mean in terms of how they are related to the brain signals?

iuri,

the 2D/3D topographic maps simply display a matrix of data over the scalp. The content of this matrix depends on the processing that you perform before the actual visualization box. For example, the scenario that we provide with the OpenViBE release, computes the beta band power on the last second. This is what is displayed in the samples...

Is it clear ?
Best regards,
