Hello Carlos,
demeaned data may be problematic for FEAT - you can use the fslmaths to add an arbitrary mean ( say 1000 ) back into the data.
Hope this helps,
Kind Regards
Matthew

However, when I try to run a GLM with the concatenated demeaned file as input, Feat crashes. After reading the manual, I understand that FILM tries to remove the mean from the data as a first step of GLM. Since my data are already demeaned, I suppose this causes Feat to crash.
