[Insight-users] Error using MultiResMIRegistration

[Vicente Grau]

Hello,

I'm trying to use the MultiResMIRegistration program on two 3D volumes 
that I've created. The parameters file that I'm using now is:
------------------------
Img_1.raw
1
100 100 20
0.293 0.293 1.6
Img_2.raw
1
100 100 20
0.293 0.293 1.6
0 1 2
0 0 0
5
4 4 1
4 4 1
2500 2500 2500 2500 2500
1e-4 1e-5 5e-6 1e-6 5e-7
320
Registered_1
---------------------------

I've tried also other combinations of parameters, but the result is 
always the one shown below:  the program always aborts immediately after 
starting with the first level. The directory Registered_1 exists, I've 
created it previously. Do you know what's happening in this case?
