Hi Lara, Those stat images are in exactly the same space as the example_func image (i.e., the middle time point within your 4D time series). However, you can put them into whatever space you want using the matrices/images within the .feat/reg folder (see FLIRT documentation and posts).

Hello, I am running a simple fMRI block design for individual subjects in FSL and have a simple question. Within each subject's .feat/stats directory, there are a set of tstat.nii.gz images. Are these tstat images registered to the subject's individual anatomical scan? To their mean functional scan? or both? Thanks so much, Lara
