External Email - Use Caution
Hi Dr. Greve,
I apologize, maybe I should have been more specific. What I meant to say was, for example, in the attached area and volume distribution graphs over regions, we have most outliers in the superior frontal, and inferior parietal regions. However, on examining these regions for the subjects that are outliers, in comparison to the other subjects that are not, there doesn't seem to be an increased inclusion of voxels in these regions which could possibly explain why these might be outliers compared to the rest of the group.

When you say that you looked at the labels/segmentations and that nothing looked horribly wrong, would that mean that the labels are accurate and that they are not really outliers?

The primary reason for my wanting to do this is due to a large number of outliers in terms of area and volume. Our subject population is cognitively impaired older adults > 60 yrs. The custom surface based template might help in investigating the area outliers, but it wouldn't help in investigating the volume outliers. Since the DK atlas is constructed from a population 18-86 years including 10 people with Alzheimer's Disease, I am not even sure if making a new volume atlas would help. > > Attached are graphs showing the distribution of the region wise area, volume, and thickness of all subjects in lh (filled circles) and rh (open circles). I looked into the aparc and aseg labels in specific regions for the subjects that are outliers, but nothing seems to have gone horribly wrong in terms of parcellation. Any pointers on how I can investigate and if a custom volume template might help? > > Thanks, > Nandita > > > > On 12/5/19, 1:36 PM, "freesurfer-bounces@nmr.mgh.harvard.edu on behalf of Greve, Douglas N.,Ph.D." <freesurfer-bounces@nmr.mgh.harvard.edu on behalf of DGREVE@mgh.harvard.edu> wrote: > > We currently do not have a mac build of mri_aparc2aseg, and we recommend > downloading the freesurfer dev release to resolve this issue. > > > > On 12/5/19 1:00 PM, Joshi, Nandita wrote: > > External Email - Use Caution > > > > Thank you so much for that! The README file instructs to download make_average_subject and platform specific mri_aparc2aseg. However, the mac version of mri_aparc2aseg is missing in the patch.
