Liang,
mri_annotation2label will separate all the ROIs in the ?h.aparc.a2009s.annot - is this what you need? I'm not sure what you mean by "mask image based on this image using 1, 2". You can merge or split labels as well.

To display aparc.a2009s+aseg.mgz in tkmedit, you can do:
tkmedit subjid orig.mgz -segmentation aparc.a2005s+aseg.mgz

Hi FS experts,

Does anyone know how to extract these ROIs (including all gyral and sulci)
from the image <aparc.a2009s+aseg.mgz>. I just want to create a mask image
based on this image by using 1, 2, .. to code different brain areas. Thanks
for your solutions.

Also, I can not display the image using the following command: tkmedit
subjid orig -aux brain -aparc.a2009s+aseg.mgz, but can correctly display
<aparc+aseg.mgz>. Any advise would be appreciated.

Liang
