Hi Carlotta,
There are many different ways to create ROI masks, such as manually
drawing, using a discrete or probabilistic atlas, or defining a
spheres areound areas of peak activation. You need to decide which
areas of the brain you are interested in, and then create a binary
mask image with 1s in those areas, and 0s everywhere else.
After you've calculated a scalar value, derived from COPE values
within your region, for each individual in your study, you can then
correlate them with your other measures as you were already trying to
do - using MATLAB, SPSS, or similar.
Cheers,
Paul
