Hello,
I am interested in creating my own atlas for elderly patients with enlarged ventricles. We have about 30 patients with axial MPR scans. Is this enough to build an atlas?
Thanks, 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

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
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?

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 if you upload a subject that is not doing well I'll take a look. Have you tried the -bigventricles flag? cheers Bruce On Fri, 11 Jul 2014, Brianna Damadian wrote:

I have not tried that yet - when would I enter this flag? During the initial recon-all coding or later? Thanks, Brianna
