Hi, Thanks for your reply. We are interested in a one-sample group mean; however, we are not sure how to do this on the Freesurfer so we can have the group mean activation on the inflated brain. We would appreciate if you could provide more information about --osgm?

We have done a group analysis using FSL (N=10), to see the average activation pattern for each body part. However, we are having problem viewing the average group activation pattern on the FreeSurfer inflated brain. We have tried to use the steps at the last section of the following link (http://fsl.fmrib.ox.ac.uk/fsl/fslwiki/FreeSurfer); however, we are not sure about the design and contrast matrix in Step 4. We were wondering if you have any suggestions about how to view the group data on the inflated brain? We greatly appreciate your response.
