[FieldTrip] band pass and segmentation

[Ivano Triggiani]

Hi all,

I tried to
use a simple cfg.bpfilter (0.1 - 40) for an EEG that I divide into 2 secs époques
and giving a look it seems that at the board of every window the signal is
reduced (just like following a parabolic trend). Is this a problem of the brutal segmentation (respect to a good windowing) or there's something else?
