Hi Andres,

I'm not sure what you mean by "way to link channels and vertices."

This seems to suggest you created your power spectrum in sensor  
space. Is this true?

If so what did you use the forward matrix for?

If you got the power spectrum values in source space (using some  
inverse solution), then the solution to your problem is easy. Just  
use one of the functions below to write those values to either a w  
file or stc file.
