Hi DARTELers,
I am using DARTEL to normalize functional images of adults between 60 and 85 to the MNI template. attached is an example of the result.
I am finding that there are areas where functional images do not normalize well to the MNI, in this example the visual/cerebellum area, but in some cases in the PFC and around the ventricles.
3 questions:
Does anyone have a suggestion of how I might improve the quality of normalization by changing parameters of DARTEL?
Will skull stripping before aligning all the functionals and structurals yield a worthwhile improvement?
Is there anything I can do to improve normalisation or is it a limitation of trying to normalise this age range to the mni?
