Hi all,
I have been trying to figure how to calculate the surface area for subcortical ROIs. The ROIs are from the Oxford-GSK-Imanova structural and connectivity striatal atlases and the Oxford thalamic connectivity atlas. These ROIs were mapped onto each subject's brain (so I am trying to find the surface area of the ROIs in each subject).
Other implementations I have seen for obtaining the surface area of subcortical ROI's have required .vtk files or another kind of mesh/surface format. However, I only have the data in .nii format. Does anyone have any advice as to how (or if) I can calculate the surface area for these subcortical structures?
Thanks in advance!
Stuart
