Hello,

I am trying to perform between-subject statistics on cortical DTI data in certain ROIs.

I can do this by overlaying the DTI data on the surfaces on tksurfer, load and mask the label with the ROI, and then go to File -> Save Overlay. After doing this for all subjects I can perform statistics on the output files.

However, it is not practical to do this for all >200 subjects for each ROI. Is there a way to go about this process on the command line?

Thank You, Jordan Chad
