[FieldTrip] 60 Hz notch using preprocessing

[Francesco Di Pompeo]

Dear all,

I need a 60 Hz notch filter before the ICA of continuous 4D data.
I did it using ft_preprocessing but the 60 Hz line is still there..

Something wrong in my script?


cfg = [];
cfg.dataset = '0';
cfg.channel    = {'MEG', '-A246', '-A170', '-A110', '-A19'};

cfg.bpfilter      = 'yes'; 
cfg.bpfreq        = [1 150];

cfg.dftfilter     = 'yes';
cfg.dftfreq       = [60 120 180];

data_meg                 = ft_preprocessing(cfg);
