Hi Everyone,
I have some multiband epi data. I used topup to correct the distortion in the data and that has worked well. However, for about 5 (out of 30) Ss, the spatial normalization fails miserably. For spatial normalization, I am using non-linear transformation and I notice with linear those 5 Ss register quite well.
Here is my question: Should I just use linear transformation for those 5 Ss? If so, should I also use linear transformation for the remaining 25 Ss so that my pipeline is consistent across subjects (upon visual inspection, their registration look good with linear or non-linear, but I understand that non-linear is more optimal).
Many thanks for your time,
DJP
