This could happen easily if you are using Caret5 and the same
visualization specification for both hemispheres. If you have both
metric files loaded, but the same metric overlay is set to apply to All
surfaces (see top of metric selection page selection on D/C menu).
Are you mapping to PALS_B12 or fs_LR? September 2006 tutorial has
separate LEFT and RIGHT standard scenes visualization specifications. I
confess I still use them, to keep myself un-confused.
If you do have both the LEFT and RIGHT mapping metric columns loaded in
the same session, try toggling from one to the other. Are they still
identical? (Alternatively, you can press the H button on the D/C metric
selection menu for each column, and see if they are identical.) If they
really are identical, then something went wrong during the mapping
(target surface selection, possibly).
But let's start with these checks before building a whole tree of
possibilities. ;-)

I have generated two sample t-test results spmT_0001.hdr/img, and i
tried to map it to the surface. The result was strange, the left and
the right hemisphere were activated completely the same. In fact, the
left and the right hemisphere were activated different. How can i get
the correct results when the left and the right hemisphere were
activated differently?
