[FieldTrip] global field power

[Nenad Polomac]

Dear Jan and Elke,

Thank you for your ansewers!
I have applied The Matlabs std function on data.avg matrix and
it doesn't give me good results. Namely, it returns matrix with  [1 x time
points] so it reduces number of channels to one, which is not what I want.
I believe this is because the sum function sums data column-wise. My
question is could I do only sqrt(data.var). Would this result be proper way
of calculating global field power?

All the best!

Nenad
