General question of preprocess in DTIprep
1. Is there a registration procedure in DTIPrep that performs an
affine registration of the diffusion-weighted images prior to
motion and eddy-currents correction?
2.When correcting for subject motion, if there is a rotation of the image involved in the image registration, then the same rotation must be applied to the encoding vectors. I wonder whether rotations that are applied to a given diffusion-weighted volume are also applied to the encoding vectors in DTIPrep automatic pipelines?
3. If SNR is not low, is denoising still recommended?
