Hi, When I run a whole-brain search-light analysis with non-overlaping lights (each voxel participates only in one light) I get about 3000 lights (half a hour classification). Running 1000 times such permutation analysis would obviously take weeks. And this is a limited non-overlapping lights case. Is there any more realistic approach? I found here that people ran permutation analysis only 10 times while they stack the predictions of all voxels together to have their chance distribution: http://cercor.oxfordjournals.org/content/early/2011/12/20/cercor.bhr357.full (see "Searchlight analysis" section second paragraph). Does it make sense for you?
Thanks, Vadim
