Randomise in DTI analysis

Dear Beatriz,

with TFCE correction the p value is not alone a function of t (as in univariate parametric statistics), but now also depends on the size of the cluster a given voxel is part of (within a large cluster moderate t-values can yield very low p-values; the same t-value in a smaller cluster would yield a higher p-value).

Best,
Jens
