Hi,

Many thanks for your reply.

The matrix output of ‘tbss_2_reg –n’ is as follows:
0.90421  -0.0804094  -0.0109341  23.2267  
0.0877737  1.13531  -0.00645942  -24.8751  
0.0309127  0.00256656  1.03222  -8.86239  
0  0  0  1
The matrix output derived from using flirt command line is as follows:
0.897359000000000  -0.0654672000000000  -0.00624482000000000 21.1891000000000
0.110815000000000  1.09141000000000  0.0203711000000000 -22.9668000000000
0.0219017000000000  0.0250182000000000  1.04106000000000 -11.4406000000000
0  0  0  1
The ‘.mat’ file generated from ‘tbss_2_reg –n’ should be consistent with that obtained from using flirt command line. However, the two ‘.mat’ files are different from each other. I don’t know what the problem is.
I would be very grateful if you could give some suggestions.

Many thanks again.
