Hi I am having difficulty using the "normalize to MNI space" function of dartel. The steps I've taken are as follows 1) Import seg_sn.mat files 2) Create template: I used just the rc1 files. 3) Normalise to MNI space- Selected c1Template6. Selected the flow fields and selected the rc1 images. It produces this error Running 'Normalise to MNI Space' ** Affine registering "c1Template_6" with MNI space ** Failed 'Normalise to MNI Space' Attempted to access df(4); index out of bounds because numel(df)=3.
