²Solutions to these problems:
åAdd appropriate shift to E2 on top of rotation
íAllow for xyz shifts between days (E1-E2), and center shifts between EPI and SPGR (E1-S1 and E2-S2)
åPad EPI datasets with extra slices of zeros so that aligned datasets can fully contain all data from all sessions
åZero padding of a dataset can be done in to3d (at dataset creation time), or later using 3dZeropad
å3dvolreg and 3drotate can zero pad to make the output match a Ògrid parentÓ dataset in size and location
