Hi all, I want to remove DC offset before applying the high-pass filter. I was wondering if I can achieve that by putting cfg.detrend = 'yes' before cfg.hpfilter = 'yes', something like:
cfg = ;
cfg.dataset = filename_raweeg;
cfg.detrend = 'yes';
cfg.hpfilter = 'yes';
cfg.hpfiltord = 2; % Order of the filter = 2.
cfg.hpfreq = 0.1; % High-pass cutoff at 0.1 Hz;
[data] = ft_preprocessing (cfg);
Thank you in advance.
