[FieldTrip] Question regarding cluster-based permutation test

[Stephen Politzer-Ahles]

Hello Faranak,

If you're doing a within-subjects design, then testing channels*time*freq
on grand average data should be possible; see
http://fieldtrip.fcdonders.nl/tutorial/cluster_permutation_freq#within_subjects_experiments
.

Best,
Steve

X
