Hello. I've noticed that several of the afni_proc examples use -volreg_align_e2a such that the inverse of the transform from aligning the anatomical image to the EPI is applied along with motion correction. What are the important factors when deciding whether to just align the anatomical to the EPI or whether to add in -volreg_align_e2a. Thank you!
