Dear Freesurfer users and authors,
Is it possible to export a surface (eg. ?h.thickness) to an image volume -
something which could be read into SPM?
I came across mri_surf2vol function, however I am not to familiar with the
usage. I understand that a volume registration file is required,
Dear Freesurfer developers,
I'm wondering whether the wmparc.stats is computed with a partial
volume correction at the boundaries of the structures.
Thank you,
Nasim

Hi Mayuresh,
what do you want to do with it in SPM? The thickness can be converted to
a volume format, but it will actually be a 1 x n vector, where n is the #
of vertices in the surface. Not sure if that will be useful or not. For
example from the surf dir you could do:
mris_convert -c
FYI

Hi all,
I am calculating total gray and white matter volumes using mrs_volume
and mris_wm_volume, and I wanted to clarify what these are
measuring. I am following the instructions on the morphometry stats
wiki page, which say to use mris_volume and subract wm from pial
volume to get total
Hi Dana,
this will compute all supra-tentorial white matter and *cortical* gray
matter volume. The mris_wm_volume binary computes the interior of the
?h.white surface, then throws out the volume of all the non-wm structures
in the interior. I guess the BrainSetNotVen value is a reasonable one
Dana,
Here's an approach that I use for total brain volume (without the
cerebellum):
Compute the total volume enclosed within the pial surface (mris_volume
lh.pial) and then subtract out the volume from the aseg.stats for the
Lateral-Ventricle and choroid-plexus). Repeat for both hemispheres,
Hello - can anyone tell me where I can find details on what aseg stats include
and exclude from each measurement? The ones I need in particular are:
Left-Cerebral-White-Matter Left-Cerebral-Cortex and IntraCranialVol. I'd
like to understand if L-Cereb-Cortex means just gray matter,
If you visualize the segmentation (aseg.mgz) in tkmedit you can see
exactly what is labeled Cerebral-White-Matter and Cerebral-Cortex based
on the volume (not the surface) segmentation.
As for the Intracranial Volume value in the preamble of the aseg.stats
file, that is a statistical estimate of
Dear all,
1-Is there a way to use mris_anatomical_stats
to calculate mean ROI values on the re-sampled and smoothed individual
subject data that is produced in the pre-processing step, rather than
mapping the ROI back to each subjectsrsquo; space? If so what is the
command?
