If it is in progress, it means that it is not usable by end-users yet? If so, when would the how-to guide be available?
(This would be a wonderful tool for my project in which I need to see a particular region labeled, i.e., lateral portion of the areas between parietal and occipital lobes. I am talking about the 'purple-colored' region in the example image shown in the Wiki page)
Thanks.
Nam.

Lars,
The wiki page describing atlas-building is a work-in-progress, so it's not yet a how-to guide, but the essential information exists. See:
https://surfer.nmr.mgh.harvard.edu/fswiki/CorticalParcellation
If you decide to try to construct your own atlas, it would be helpful to email me particulars on trouble-spots, so that the wiki page can be improved.

Hi Lars,
I guess in principal you could use it via the standard route for spherical morphing if you segmented it yourself. In general we haven't done a lot with cerebellum as you need something like .3 mm voxels in plane to resolve the majority of the foliations. Could someone point Lars at the wiki page describing how to build your own atlas? Analyze would probably be okay if you keep the orientation info in an associate .mat
file
(as SPM does)
cheers, Bruce
