[Eeglablist] Is power calculated in STUDY and in dataset is abs or relative?

[Tarik S Bel-Bahar]

Greetings Abdul,

I am not an expert on the mechanics here,
but I believe if you are referring to ERSP computation using the newtimef
function,
then the baseline of values before the 0 time point in your epochs is
automatically subtracted.
Please also see  multiple messages on this topic in recent months in the
eeglablist archives.

Respectfully,
Tarik
