Hi Marisa,
if you search for "no significant voxels" in the list's archives at
https://www.jiscmail.ac.uk/cgi-bin/webadmin, you will find >50 hits.
Assuming all the processing and the masking went right, the most likely
reason in your case may be the low number of subjects, in which case you
could try SnPM which is more powerful especially when dealing with
smaller groups.
Hope this helps,
Marko
