You can figure out the transform by looking at the two matrices in the NIfTI headers of the rc*.nii files. Nii=nifti('rc1blah.nii'); Nii.mat Nii.mat0 Mapping from a voxel i,j,k in the rc* to the corresponding location in the original scan can be done by: Niir=nifti('rc1blah.nii'); Nii=nifti('blah.nii'); Nii.mat\Niir.mat0*[i; j; k; 1] Best regards, -John On 10 November 2011 18:36, Goldman, Aaron (NIH/NIMH) [C] <[log in to unmask]> wrote: > Hi, I had a question about the “New Segment” application in SPM8, > specifically the “Native + DARTEL Imported” output option.
