We will show how to do spatial realignment, slice-timing correction, spatial normalization to the MNI template (2 different ways), and spatial smoothing. Overall, there are many different ways to order these operations, with different options, so this ... WebOverall the spm12_realign does the realignment. There is some discussion of performing realignment before slice-timing correction because estimation of motion parameters may …
