Hi - FSL uses Analyze format images like those in the FEEDS example data
set. These have a pair of files for each 3D/4D data set - a .img data file
and a .hdr header file.
The results you have got with the FEEDS test are actually fine - it is
just that some of the F-test checks now fail because we changed (patched)
the F-test part of FEAT recently (but haven't yet updated FEEDS data to
match this software change).
Thanks, Steve.
