what is your input data format?

Dear Bruce,
Thank you for your reply.
However, we are obtaining an odd result with FreeSurfer when we examine the volume of the left
and right accumbens. In the UK BioBank data >20K subjects freesurfer segmentations the
left accumbens is clearly significantly larger than the right accumbens (
http://biobank.ctsu.ox.ac.uk/crystal/label.cgi?id=110
<http://biobank.ctsu.ox.ac.uk/crystal/label.cgi?id=110>). Also, the attached paper used
freesurfer and found left accumbens > right. In our hands, and in 2 different data sets
collected in two different sites, we obtain the opposite with FreeSurfer (right accumbens
> left accumbens).
Furthermore, when we segment these same data sets with FIRST from FSL we do obtain
Left accumbens > right Accumbens in both data sets in agreement with the
literature.
Any help in solving this discrepancy is much appreciated.
Regards,
Paul

External Email - Use Caution
Hi;
I am wondering if the orientation of the input data to recon-all (i.e.
Neurological Vs. Radiological)
produces different results in terms of laterality (right vs. left)?
Thanks;
