Hello Dear Fieldtrip users,
I have an EEG signal which I want to do artifact rejection on it.I've recorded the EEG during watching a video clip.
My signal is 100 seconds and I've selected 50 seconds.I can find EOG artifact but I can't reject it. Would you please let me know how can I do it.
cfg = ;
cfg.dataset = 'myfile.eeg'; %BrainVision Recoreder EEG
cfg.trialdef.triallength = inf;
cfg.trialdef.ntrials = inf;
cfg = ft_definetrial(cfg); trl = cfg.trl;
data_org = ft_preprocessing(cfg);
%Select 30sec of data
cfg.latency = 'all';
cfg.latency = [0 30]; %start point and end point
cfg.avgovertime = 'no';
cfg.nanmean = 'no';
data_s = ft_selectdata(cfg, data_org);
[cfg, artifact] = ft_artifact_eog(cfg,data_s);clean_data = ft_rejectartifact(cfg,data_s);
