RE: "NORMS_" output files from denoising
Hi Yuta/Jennifer/Shady

Good eye, those new files contain the power (root mean square) of the BOLD signal at each voxel, computed before and after band-pass filtering (during Denoising, after removal of confounding effects). They are mainly used to compute the ALFF and fALFF measures (in voxel-to-voxel first-level analyses).
