Dear SPMers:
I have a coordinate [x,y,z] in 3D image 'abc.img'(with
[0 0 0] as orgin in abc.hdr, dimension [101 111 121]),
I want to know it MNI coordinates.
I coregistered 'abc.img' to 'T1.mnc', then I got the
.mat file (let us say, 'abc.mat'). I get
transformation matrix ABC (4*4) from 'abc.mat'. Does
my MNI coordinate suppose to be
ABC * [x-101/2 , y-111/2, z-121/2, 1]' ?
Could you please tell me where is wrong?
Thank you very much!
Weiying
