[FieldTrip] Cluster-based permutation tests on event related potentials

[Zdenko Kohút]

Hi Antonio,

There is a toolbox for Matlab designed specifically for permutation testing
of ERPs, including the cluster corrected version - 'Mass Univariate ERP
Toolbox' and you it works with data in EEGlab format (.set); url:

Best regards,
Zdenko
