Hi Bruce, Sorry for so many responses. I figured it out that I can visualize it using tksurfer.
Besides this, can I visualize it in freeview, CARET, or some other tools? My goal is to display the ROI on a fsaverage inflated surface. If it can be done in freeview, could you give me some instruction? In freeview, I found that I can only load ROI after I load a volume, but not after I load a surface. Thanks!

So I ran the following and obtained all the DK ROI labels. mri_annotation2label --subject fsaverage --hemi rh --outdir <my_output_dir> Then, I am wondering how I can use the label files. For example, can I overlay it on a brain in fslview? The label file has many lines. Could you suggest what document I can read in order to interpret it? One of them is like, "1530 47.244 -41.285 -1.841 0.0000000000". Thanks for your help!

The atlas itself is a compilation of multiple statistics and not easily visualizable (except for the prior probability I guess). cheers Bruce On Tue, 16 Jul 2013, Yang, Daniel wrote: Hi Bruce, I am sorry, I mean, is there a DK atlas on a standard template brain (like MNI 152)? sorry, I don't know how DK atlas works. Is it a probabilistic atlas, or dependent on the exact folding pattern of the unique individual? (I guess it's the latter). I'd like to generate a ROI brain mask for a specific region on the DK atlas, independent of the individual I ran. Having said so, I guess I can just run recon-all on a MNI 152 brain, so that I can get the ROI maps.

The DK atlas is estimated on every brain that you run recon-all on and stored in the label directory. Is that what you want? cheers Bruce On Mon, 15 Jul 2013, Yang, Daniel wrote: Dear FreeSurfer Expert, I would like to draw the specific ROI of the DK atlas (not specific individual, but this ROI in general). I'm wondering how this ROI can be extracted/created as a mask so that I can draw it on the brain using some software? Could you please advise?
