Hi Brianna
if you upload a subject that is not doing well I'll take a look. Have you
tried the -bigventricles flag?
cheers

Hi Bruce, I'm using v5.3.0. Does this version do well with patients with large
ventricles?
Two cases I ran seemed to do well with the ventricles, but some others seem to
be running into some errors (which I
haven't had the time to work out yet).
So in your opinion, to get our desired measures of total gray matter and
ventricular volume, we would not need to
create our own atlas?
Side question: Is there any literature on/do you happen to know what the margin
of error for a measure like total
gray matter (taken from the aseg.stats header) is in Freesurfer?
Thanks,
Brianna

Hi Brianna
yes, that would work (although you would use freeview or tkmedit).
Why do you feel you need a new atlas? Our latest version does quite well,
even on subjects with very
very large ventricles. What version are you running?
cheers

Hi Bruce, Would be interested in an atlas for aseg that gives total
gray matter and
ventricle volume.
Would I be able to create an atlas based on these 30 patients with
labeled volumes for just
these measures?
Additionally, my understanding of creating an atlas is very
rudimentary - would I begin the
process by running
recon-all on these 30 scans and then manually editing the
segmentations using tksurfer?
Thanks again,
Brianna

Hi Brianna
what kind of atlas do you mean? If one for creating the aseg
you will need
to have labeled volumes for creating a new atlas
