Hello AFNI experts,

I have used 3dAllineate to transform an MNI template to a participant's diffusion space (their FA image). I then use this transformation to warp an ROI (originally in MNI space) to the participant's diffusion space. Unfortunately, the corpus collusum is slightly misaligned on my first transformation, so this affects my ACC ROI registration. I used nearest neighbor interpolation.

Are there any othe tricks I can try before resorting to non-linear warp?

Thanks,

Emily
