Almost. This will include medial wall voxels that are not GM. It will also not include subcort GM. It is better to use aparc+aseg.mgz and merge the GM ROIs together. On 1/15/17 1:01 AM, Zhivago wrote: Hi, Are the lh.ribbon & rh.ribbon volumes the GM estimate from reconall? Can I used

mri_aparc2aseg output a volume 256? 0.35 isotropic will be ok. we'd prefer 0.25 if we can. best Colin -- Forwarded message -- From: Douglas Greve gr...@nmr.mgh.harvard.edu To: freesurfer@nmr.mgh.harvard.edu Cc: Date: Sun, 23 Jun 2013 20:03:09 -0700 Subject: Re: [Freesurfer] ribbon

Hi - I need to make a ribbon volume. I have all the necessary surfaces, but I'm lacking an aseg.mgz because the data is monkey. I saw one guy on the list had success by just calling his orig.mgz aseg.mgz. I tried that, and it calculated the left right pial and white distances. Men sadly it
