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
