Hi,
I can run Featquery on any one subject in my study with a voxel of interest
and as far as I understand the stats/pe gives the % BOLD change. Indeed the
values I get look about right. Since I would like to know the % BOLD in a
group of subjects in my study, I ran Featquery on grouped data by selecting
the cope.feat directory within the .gfeat directory. However, the stats/pe
produces a number around 5500, the interpretation of which I am confused
about. I am also confused about how to interpret the time plot in this
Featquery analysis of grouped data. Is there a way of getting Featquery to
work out the % BOLD in my group of subjects along with the standard error.
Would it be reasonable to find the % BOLD in each subject at a specific
voxel and then simply mean together from the different subjects and
calculate the standard error of the mean at that voxel (I have performed a
cluster analysis)? Any advice would be appreciated.
Aziz.
