Dear Freesurfer community,
I have a volumetric roi.nii file created with spm, based on MNI coordinates from the literature.
My goal is to do a roi analysis in Freesurfer, as I am interested in correlating the thickness values of this roi with a behavioral measurer.
However, I am lost as to how I can appropriately convert this volumetric roi.nii file to a label.
I hate to ask for too much, but can anyone briefly share the commands or steps as to how to convert this roi.nii file to a label so I can conduct an roi analysis within Freesurfer?
Thank you very much, Paul
