hi all,
i analyzed 5 min resting state data, using your script for spectral
analysis (thanks for that!!)
i have read a lot of discussions and unfortunately i could not understand.
the results of the script you published  are uV2/Hz or uV2?
how should i report that?
to my understanding the spectopo function uses Matlab pwelch function
which  gives us the power density, but after this, your script is using log
of the frequency band so i cant understand whether this log calculation is
moving us to uV2/Hz or to uV2?
(if i try to do step by step of your script, i understand that "spectra" is
on dB - and the log tranfer it to uV2/Hz or uV2?)

i will really appriciate your help!!
