Thank you Dan,

I got the power spectrum in source space (in matlab, after getting the
estimates).
My problem was that since I used matlab, I did not know which set of the
calculated power spectra belonged to either the left or the right group of
vertices (for left and right hemispheres).

It seems the first half of results belongs to the left hemisphere and the
second to the right one.
Is this correct?

Thanks for your comments,

-- Andrés

the functions below to write those values to either a w file or stc
file.
