Hi all!
have a problem with normalitzation process.
Mines are rat brain fmri images. It's original voxel size is 0.3125 0.3125 1(FOV 40x40x1, Matrix 128x128)
In order to process them with spm, I multiply by a factor (10) the voxel dimensions ==> 3.125 3.125 10.
I realign and coregister the images without problems, but when i try to normalise (I have a rat brain template), spm says:
------------------------------------------------------------------------
Running job #1
------------------------------------------------------------------------
Running 'Normalise: Estimate & Write'
Smoothing by 10 & 10mm..
Coarse Affine Registration..
Fine Affine Registration..
Field of view too small for nonlinear registration
Altought normalization "warning", I can do the inference (with good results) but the check-reg is not as good as desirable.
Can you please help me? Wich parameters should I adjust? Something about bounding box?
Best regads,
Javi.
