[FieldTrip] FT_REJECTARTIFACT

[Nenad Polomac]

Dear all,

I have one problem concerning ft_rejectartifact function.
I did everything as you explained in automatic artifact rejection tutorial.
I mark segments first and that is fine, but the ft_rejectartifact doesn't
remove marked bad segments form my data.
Please help!

Here is my code:

% automatic
clear all

s=[87 209 195 225 60];


for g=1:length(s)
    input_no=s(g)

    clear sub

    sub=['Subject' num2str(input_no)];
    eval(sub)   %calling subject's script


            cfg=[];
            cfg.trialdef.eventtype  = 'UPPT001';
            cfg.trialdef.eventvalue = 1;
            cfg.trialdef.prestim    = 0.1;
            cfg.trialdef.poststim   = 0.5;
            cfg.trialfun = 'trialfun_general';
            cfg.channel = {'MEG'};
            cfg.continuous = 'yes';
            cfg.dataset = [subjectdata.wr11.datadir];

            [data1]=ft_definetrial(cfg)
            trial=data1.trl;


            % muscle
            cfg=[];
            cfg.trl =trial;
            cfg.datafile   = [subjectdata.wr11.datafile];
            cfg.headerfile =[subjectdata.wr11.headerfile];
            cfg.continuous = 'yes';

            % channel selection, cutoff and padding
            cfg.artfctdef.zvalue.channel = 'MRT*';
            cfg.artfctdef.zvalue.cutoff      = 15;
            cfg.artfctdef.zvalue.trlpadding  = 0.5;
            cfg.artfctdef.zvalue.fltpadding  = 0.5;
            cfg.artfctdef.zvalue.artpadding  = 0.1;

            % algorithmic parameters
            cfg.artfctdef.zvalue.bpfilter    = 'yes';
            cfg.artfctdef.zvalue.bpfreq      = [110 140];
            cfg.artfctdef.zvalue.bpfiltord   = 9;
            cfg.artfctdef.zvalue.bpfilttype  = 'but';
            cfg.artfctdef.zvalue.hilbert     = 'yes';
            cfg.artfctdef.zvalue.boxcar      = 0.2;

            %make the process interactive
            cfg.artfctdef.zvalue.interactive = 'yes';

            [cfg, artifact_muscle] = ft_artifact_zvalue(cfg)



            % jump
            cfg=[];
            cfg.trl =  trial;
            cfg.datafile   = [subjectdata.wr11.datafile];
            cfg.headerfile =[subjectdata.wr11.headerfile];
            cfg.continuous = 'yes';

            % channel selection, cutoff and padding
            cfg.artfctdef.zvalue.channel    = 'MEG';
            cfg.artfctdef.zvalue.cutoff     = 20;
            cfg.artfctdef.zvalue.trlpadding = 0;
            cfg.artfctdef.zvalue.artpadding = 0;
            cfg.artfctdef.zvalue.fltpadding = 0;

            % algorithmic parameters
            cfg.artfctdef.zvalue.cumulative    = 'yes';
            cfg.artfctdef.zvalue.medianfilter  = 'yes';
            cfg.artfctdef.zvalue.medianfiltord = 9;
            cfg.artfctdef.zvalue.absdiff       = 'yes';

            % make the process interactive
            cfg.artfctdef.zvalue.interactive = 'yes';

            [cfg, artifact_jump] = ft_artifact_zvalue(cfg)




            cfg.artfctdef.reject = 'complete';
            cfg.artfctdef.jump.artifact = artifact_jump;
            cfg.artfctdef.muscle.artifact = artifact_muscle;
            data_no_artifacts = ft_rejectartifact(data1)
 end

Thank you in advance!
