Hi - it's impossible to know what's going wrong with this little
information - but most likely your model timings don't match the
experiment well - I suggest that you turn on the ICA option in FEAT,
so that you can see in a data-driven what what ICA thinks the
activation and activation timecourses look like.
Cheers, Steve.
