Here's a basic one: I have 16S subjects, each one with 3 run's. Is it o,k on the FEAT.gui on the First-level analysis to leave the initial and main structural image tabs un-marked, using only MNI152 as standard space? This means not using the Ss high-res anatomy file. How does that effect my first/higher levels? what are the adv' / disadvantage? Many Thank's Ram
