Hi Doug,
Thank you so much! Because I will do the analysis using SPM, I need the
coordinates in MNI152 space. I found a transformation between them:
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]
Is this transformation correct?
I guess I can then get the MNI152 coordinates in this way:
P305 = [MNI305x MNI305y MNI305z 1]';
P152 = M*P305
Am I correct?
Best wishes,
Baojuan

Hi Baojuan, that coordinate will be mni305 space. Is that what you want?
