Brad,
I agree that AFNI's TTatlas, which supports the Where am I feature, is
pretty much what you're looking for, but it is in AFNI's +tlrc space --
not MNI152.
Another option is to use Caret5:
Download our colin atlas dataset
(http://brainmap.wustl.edu/caret/tutorials.03-06/TUTORIAL.1.HUMAN.03-12.tar.gz
-- almost 200Mbytes compressed, almost 500Mbytes extracted).
gunzip TUTORIAL.1.HUMAN.03-12.tar.gz
tar xvf TUTORIAL.1.HUMAN.03-12.tar
cd TUTORIAL.1.HUMAN.03-12/HUMAN.COLIN.ATLAS.03-12/LEFT_HEM
caret5
make sure you select either the SPM2 or SPM99 fiducial surface and that
no other fiducial surfaces are selected
make sure the areacolor file and BRODMANN areal estimation file are selected
switch to the flat map
D/C: toggle on Areal Estimation
This color lookup will be handy:
http://brainmap.wustl.edu/caret/slides/human.03-06/sld014.htm
File: Open Data File: Volume Anatomy File, and navigate to where you
have a left-on-left version of avg152T1.img/.hdr; select that volume.
Window: Viewing Window 2: switch to VOLUME view
Click on an area on the flat map that is in the Brodmann area that
interests you, and see where the volume crosshairs go.
Click on a voxel in the volume, and see what the Identify Window reads
out (e.g., Areal Est: Brodmann: BROD.17 0.4 BROD.18 0.3 BROD.19 0.2
BROD.37 0.1)
