Hello SPM users,
when we use DARTEL for spatial normalization
of EPI images, we came across the following problem:
With the newsegment function, we get the segmentation
quality that serves DARTEL really nicely, however,
I cannot get the r-images in the resolution of 2x2x2,
as desired, despite defining the 6 tissue probability
maps in this resolution.
(For this purpose I had split and resliced the multi-
layer image TMP.nii into 6 separate images for each
compartment in the resolution of 2x2x2 mm3. I checked
the 'tpm' variable of the *seg8.mat file, and here
it seems the right tissue probability maps are defined)
Still, the resulting rc1- and rc2- images for GM and WM
remain in the 1.5 x 1.5 x 1.5 mm3 resolution...
What needs to be changed here to switch the whole DARTEL
process to 2x2x2 mm3 (but using newsegment)?
Thanks for any help,
