Dear
Andrew,
Is
this a test? ;-) There's an awful lot of points in there. Let's assume you
work with humans and have normalised to an MNI/ICBM152 compatible template. In
that case you can work out which points are in the thalamus by overlaying your
results onto one of the MNI/ICBM152 templates. In addition, there are all kinds
of aids and atlases out there to help with localisation, for example AAL, our
atlases, the WFU atlas, UCLA and MNI tools, etc.etc. (see
archives for this helpline). If you're specifically into thalamus, you'll end up
with Schaltenbrand/Wahren one day. As for "the basal ganglia", there are
several, so you'll have to be more specific!
Before
worrying about localisation I would have a careful look at the data - why is it
so pixelated, and why don't you get bigger blobs? The main things to look for
are smoothing and multiple comparisons correction. Looking at unthresholded SPMs
will give you a much clearer idea of what is happening
where.
Sounds
like you'll have hours of fun...
HTH,
Alexander
In this picture what 3D point
(x,y,z) would be the thalamus and what point would be the basal
ganglia.
