Hi Daniel,
no, sorry. The gca
Hi Daniel,
no, sorry. The gca is not a cortical atlas. Those labels are stored in
the .gcas file and aren't in the same space (in fact, they are in a
surface-based spherical coordinate system and not in the volume at all,
so not easily combinable).

Hi Daniel
it's in .gca format, and includes information that wouldn't fit in a nifti
file (e.g. markov relationships). You can use mri_convert to extract some
of the basic info though (e.g. the most likely class at each location and
the mean intensity of the most likely class) using mri_conver
Thanks Bruce,
When you say the atlas itself is included in the Freesurfer distribution,
do you mean there is a 3D version of it available in the download?
Also, I am not looking for the individual subjects' images, I just want a
copy of the final atlas as a 3D image in analyze/nifti format. (i.e.
Hi Daniel,
1. Do you mean the atlas or the parcellation of your subjects? We cannot
distribute the individual subjects in the atlas as the data was collected
under an IRB long ago that didn't include this. The atlas itself (summary
statistics derived from those subjects) is included in the Fre
Dear experts,
I have a couple of questions regarding the cortical parcellation atlas that
is used in Freesurfer:
1) I would like to know if it is possible to obtain the Desikan-Killiany
atlas in 3D analyze/nifti format. With each region of the brain assigned a
discrete integer number (for example
