Dear SPMers,
the SPM8-DARTEL manual for normalisation of fMRI data states: "In principle (for a random effects model), you could run the first level analysis using the native space data of each subject. All you need are the contrast images, which can be warped and smoothed."
Does this mean that I would run the first level analysis on unsmoothed native space data? Or would I also smooth the native space data before first-level analysis and then again the warped contrast images for second level analysis?
I´m using resting state data and the "first-level analysis" would be the creation of individual functional connectivity maps.
Thanks in advance,
Michel
