I did an ordinary preprocessing, followed by: cfg = []; cfg.method = 'mtmfft'; cfg.output = 'fourier'; cfg.taper = 'dpss'; cfg.tapsmofrq = 2; cfg.foilim = [0 data.fsample/2]; freq = ft_freqanalysis(cfg, data); the error I get is: Error using sfactorization_wilson2x2 (line 55) frequency axis is not evenly spaced line 55: dfreq = diff(freq); if ~all(dfreq==dfreq(1)) error('FieldTrip:connectivity:sfactorization_wilson2x2', 'frequency axis is not evenly spaced'); end indeed, the freq-axis is not *exactly* the same: >> range(dfreq) ans = 2.8422e-14 >> dfreq(1) ans = 0.6667 does it make sense to work with identical here? If so, what arbitrary tolerance should we take?
