Hi,
Yes - there's the paper by Tom listed at the top of the FSL randomise
manual webpage, that's very useful.
If you take the vox_tstat (uncorrected) or max_tstat (corrected)
you'lll get p-value images. You can then use tools such as avwstats++
and FSLView to find out where the voxels were significant - see the
randomise manual.
Cheers.
