Hi, John and SPMers:
I am using the SPM5 high dimensional warping to analyze longitudinal T1-weighted MPRAGE images. Do I need do any additional bias correction to the late scan to make it comparable to the early one? If yes, how should I do it (use SPM5 segmentation tool to output the bias corrected image in original space?) ? Thanks!
best,
