Hi Matthew,
I’m afraid they aren’t in standard FEAt directories, as I have actually processed the images outside FSL using SPM. I’m in the middle of comparing several methods across softwares, and FEAT is just the latest one that I’d like to test.
There may not be a standard space image in FSL that corresponds to my images - in fact I’m pretty sure there isn’t, as my voxel size is 1.5 mm (I think only 1mm and 2mm exist as standard in FSL).
Perhaps randomise didn’t fall over (it uses the same SPM processed images) because it has no need for a standard space image?
Cheers,
Donal
