Hi SPM and VBMers,
I use the toolbox VBM5 to create mean image with the function check sample
homogeneity...
And I notice the ouput mean image is not exactely the mean of the input
images. Some voxels have not the good intensity.
So I try to execute the function point per point in matlab and I find that the
final 3D matrix create after the mean calculation is correct. So i think the
problem is when the image is write on Nifti file. So I don't understand why
some voxel have their intensity change.
then, is exist other ways to create a nifti file of a 3d matrix ?
thanks for your reponse or advice
Vincent
