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)?
