Hi Yang, I've computed a matrix that should do the trick. If you are in
matlab, then

M = [    0.9975   -0.0073    0.0176   -0.0429
     0.0146    1.0009   -0.0024    1.5496
    -0.0130   -0.0093    0.9971    1.1840
          0         0         0    1.0000]
P305 = [MNI305x MNI305y MNI305z 1]';
P152 = M*P305

Can you give this a shot and see if it makes sense? It will probably be
hard to tell since the matrix is pretty close to identity.
