Re: [Freesurfer] subtracting segmented volumes

Have you tried using mri_label2vol with the aparc as the input instead of the aseg? doug

mris_calc should do what you want (although the aseg is not zero in the cortex, so you will change the cortical labels)

Hi, Is there a way to subtract segmented files in freesurfer? For example, aparc+aseg.mgz - aseg.mgz= aparc.mgz only? I am interested in looking only at the cortex. I find that label to volume conversion doesn't give me a nice segmented cortex, with some patchy areas of intensities lost.

thanks, AJ
