Dear Antonio,
It sounds like there really was no activation for the contrast 1.
If this happens in FEAT the report will only show the maximum Z stat
time series (was the maximum value small?), but no activation image or
mean time series. Everything seems consistent with this.
In this case it is worth reconsidering your experiment and design matrix
set-up to see why you might not have had any activation with this
subject.
You can also look at the raw, unthresholded stats images in the stats
subdirectory to see if it is a thresholding issue.
Best wishes,
Mark
