Dear FSL-experts,
I am analyzing data collected from N subjects at two different timepoints. I wish to investigate, for each voxel, if there is any significant difference in the mean activity between these two timepoints. There is no information about paired t-tests in the randomise user guide, I suppose that the reason is that data from the same subject are not independent and complicates permutatation.

Is the best solution to calculate the mean difference for each voxel and then simply run a one sample t-test with randomise?
Regards,
Anders
