Hi Everybody!
I would like to obtain the coherence value in specific frequency ranges (e.g. gamma) but in the "Coherence NxN" Pipeline editor only the "Highest frequency of interest " can be changed, the lower limit can't.
Is there a solution for this problem?
Thank You,
Ádám
Coherence is, like the PSD, computed for all the spectrum (ie. all the frequency bins of the Fourier transform, from 0Hz to half of the sampling frequency).
If you want to average some coherence bins in a larger frequency band, use the process "Frequency > Group in time or frequency bands" after computing the coherence.
Thank you for the valuable response, Brainstorm is awesome!
