Hello all,

I'm following the SIFT tutorial, the section is about filtering,
talk about eegfilt, about the zero-phase (acausal) filter

Is better forget this section of filtering and use the recommendations in
the past emails?

Are these recommendation critical for the analysis?, I mean, there is a lot
of work about MVAR models in ECoG data

Best wishes
