Cyril,
Are you talking about non-stationary cluster extent correction in VBM5?
In that case you can cite these two papers:
Worsley KJ, Andermann M, Koulis T, MacDonald D, Evans AC (1999).
Detecting changes in nonisotropic images.
Human Brain Mapping 8: 98-101.
Hayasaka S, Phan KL, Liberzon I, Worsley KJ, Nichols TE (2004).
Nonstationary cluster-size inference with random field and permutation
methods.
Neuroimage 22:676-687.
Also there is a good example in
Moorhead TWJ, Job DE, Spencer MD, Whalley HC, Johnstone EC, Lawrie SM
(2005).
Empirical comparison of maximal voxel and non-isotropic adjusted cluster
extent results in a voxel-based morphometry study of comorbid learning
disability with schizophrenia.
NeuroImage 28: 544-552.
Hope this answers your question.
