Hello SPM users,
I have a simple question (I hope). I have completed a multi-subject (6)
multi-condition (3) fmri study. I have completed individual analysis and
am working with a fixed effect group analysis because my degrees of
freedom are too small. I am interested in the best method to determine
the area(s) that are activated in the study population across all three
conditions. In other words, what are the common areas activated across
the three conditions in this study. If anyone has suggestions I would be
grateful.
Another unrelated question. What is the best technique to make a mask
image to use for ROI analysis. I have some data that I want to apply a
mask for analysis and for display but do not know how to make a
mask.img. I know the coordinates and the size of the areas I would like
to include in the analysis.
Thanks in advance.
Paul
