Have you tried using mri_label2vol with the aparc as the input instead of the aseg? doug On 04/14/2012 12:06 PM, Bruce Fischl wrote: > mris_calc should do what you want (although the aseg is not zero in > the cortex, so you will change the cortical labels) > > cheers > Bruce > On Sat, 14 Apr 201

mris_calc should do what you want (although the aseg is not zero in the cortex, so you will change the cortical labels) cheers Bruce On Sat, 14 Apr 2012, Adil Javed wrote: Hi, Is there a way to subtract segmented files in freesurfer?  For example, aparc+aseg.mgz - aseg.mgz= aparc.mgz only? 

[Freesurfer] subtracting segmented volumes

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. tha
