[FieldTrip] ft_preprocessing high-pass filtering question

[Aaron Schurger]

Hi,
When you read in a data file using ft_preprocessing, with high-pass
filtering, is the high-pass filter applied before the data are epoched
(i.e. on the entire time series for the whole data file), or is the
high-pass filter applied separately to each epoch? For very low
frequencies (with period longer than one data epoch) this will make a
difference.
Thanks!
Aaron
