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?

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.

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
