Hi Freesurfer Folks, 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, Clayton ________________________________ Clayton Swanson MS Graduate Research Assistant & PhD Candidate Sensorimotor Neuroimaging Laboratory Colorado State University Office: (970) 491-6160 Clayton.Swanson@colostate.edumailto:Clayton.Swanson@colostate.edu (He/Him)
Sorry, I don't know what you mean. Can you elaborate?

Hi Doug, Thanks for getting back to me and sorry for not being more clear. I am trying to associate TMS related inhibitory measures to the left pre- and paracentral gyrus thickness for two different groups (healthy, MS). Additionally, I am interested in measuring the associations for gait related measures (speed, cadence, etc.) to the thickness of three particular ROIs (pre-, para-, and post central gyri). While I can run these associations with the aparc.thickness output, I would like visualize the association(s) on the brain via Freeview and further only show the associations for those specific ROIs. I hope that is more clear, please let me know if its not and I’ll try to explain it better. Clayton

The only thing I have that I think will do what you want is a matlab script (annotval2surfoverlay.m, attached); copy it to $FREESURFER/matlab There is documentation in the file on how to run it. Can you look at that and see if you can make it work?
