[Eeglablist] timef: baseline and window size

[Ayelet Landau]

Dear users, I am trying to further understand the baselining that timef does
as it relates to the way the moving window FFT works. I am currently using a
prestim epoch of -200 ms with a window size of 64 ms. Using these
parameters, the output data starts around -76 ms. I was wondering what are
the parameters that determine the amount of data omitted (in this case
approximately 124ms).

In other words, when does the moving window calculation start to have enough
samples as far as timef is concerned, and should I assume that baseline is
calculated based on whatever remains before zero after an initial epoch is
omitted?

thanks
