Dear Andy,

Please allow me to point you to the fact that fieldtrip has no restriction on the type of data you want to cohere. The rather mundane reason why the tutorial documentation on coherence is about cortico-muscular stuff, is related to the fact that the interpretation of cortico-muscular coherence is far more straightforward than the interpretation of coherence between EEG/MEG-channels, or between virtual electrodes/dipoles. However, the statistical routines don't care whether the coherence spectra you pass to them are between similar channels, or between dipole locations in the brain.

Yours,

Jan-Mathijs
