[FieldTrip] Clustering analysis with One way ANOVA design

[Beom Jun Min]

Dear trippers,

I am not sure about my script for one-way ANOVA design.

I have searched in the discussion list, but I cannot find.

What I want to compare is F-statistics with different three groups, not
interaction effect by now.

cfg = [];
cfg.channel     = 'all';
cfg.neighbours = neighbours;
cfg.latency     = [0.2 0.3];
cfg.trials = 'all';
cfg.frequency = [32 32];

cfg.avgoverchan = 'no';
cfg.avgovertime = 'no';
cfg.avgoverfreq = 'no';
cfg.parameter   = 'powspctrm';

cfg.method      = 'montecarlo';
cfg.statistic   = 'indepsamplesF';
cfg.alpha       = 0.05;
cfg.clusterstatistic = 'maxsum';
cfg.minnbchan        = 2;
cfg.tail             = 1;
cfg.clustertail      = 1;

cfg.correctm    = 'cluster';
cfg.numrandomization = 1000;

cfg.design = [ones(1,36), ones(1,34)*2, ones(1,28)*3] ; % N x num of
observations
cfg.ivar = 1;

stat = ft_freqstatistics(cfg, A_zscore{1:36}, B_zscore{1:34},
C_zscore{1:28});

Is that script right?

Especially, I am not sure that the design, and tail parameters (right-sided
tail in the code) are correct.

With regards
