I would be especially interested in a comparison to t-test results. One of the examples of Golland2003 shows what to do on group-level, but in that case we are talking about a diagnosis task with patients as examples not voxels so subject classification instead of stimulus classification... Yang2012 is mentioning two studies, that use the permutation test for stimulation classification but there it is the searchlight maps that were assessed by nonparametric statistical<br />tests... From your statement 'And this gets worse in group analyses.' I infer, that there are at least tentative applications of the permutation test at group-level!?
