I have a couple of questions regarding the cortical parcellation atlas that is used in Freesurfer:
1) I would like to know if it is possible to obtain the Desikan-Killiany atlas in 3D analyze/nifti format. With each region of the brain assigned a discrete integer number (for example the all of the voxels of the left inferior temporal lobe have an intensity = 1, or the whole of the left hippocampus = 2).
2) Are the Harvard-Oxford cortical and subcortical atlases that can be downloaded with FSL the same as the cortical parcellation atlas that is used in Freesurfer? (i.e. are the neuroanatomical boundaries the same; does the left inferior temporal cortex in the Freesurfer cortical parcellation = the left inferior temporal cortex in the Harvard-Oxford atlas downloaded with FSL)
Many thanks
