Hi

Is it is possible to get **log(power^2/hz)** transformation for PSD in Brainstorm? Something like that:

Originally, computed PSD is in **power^2/hz**. Then I go to matlab command, and run **Data = log(Data.*10^12)**. Is it right formula? **All values I get are negative.** Is the outcome data divided by Hz as in the formula above (**log(power^2/hz)**)?

Can I also convert power to **decibel** in Brainstorm (**db/hz** scale)?

Thanks.
