Hi Guang,
it should be:
mri_convert atlas.gca#0 means.mgz mri_convert atlas.gca#1 labels.mgz mri_convert atlas.gca#2 priors.mgz
cheers, Bruce
p.s. sorry, I don't think the gca format is documented anywhere, but you are welcome to the code if you want

Hello, Bruce,
Thanks for your reply. I still have two questions,
- Does these gca files also include 9 arrays such as those template files saved into .tiff file.
Is there any place in the WIKI explain the format of the gca files?
What is the difference between gca#0 and gca#1?
- I tried the command line you suggested,
mri_convert atlas.gca#1 priors.mgz labels.mgz
It gave me an error message:
mri_convert: extra argument ("labels.mgz")
type mri_convert -u for usage
Thanks a lot! Guang

you can load it in tkmedit from the file menu and probe it one voxel at a time, or you can use
mri_convert atlas.gca#0 means.mgz
and
mri_convert atlas.gca#1 priors.mgz labels.mgz
to look at the most likely label and it's mean
cheers, Bruce

Hi, there,
I want to know how the FS GCA atlas looks like, is there a way to load the FS GCA Atlas and view it using tkmedit or matlab?
Is it possible to replace FS Atlas with our own Atlas and use it for analysis?
Thanks a lot! Guang
