I am wondering if it is possible to perform an ROI correlation which can then be viewed on the brain similar to whole brain GLM analysis in Freeview.  If so, how would I go about performing this type of operation as to specify that particular region. I have two groups (HC and MS) and would like to see if there is an association between paracentral gyrus thickness and performance of a lower limb motor task.  Thanks for any help you can provide,
