Hi all,
I ran an analysis on data after dividing each voxel mean across the run, and then multiplying by 100. (My intuition was that the percent signal change should be more consistent across varying SNR that the non-normalized betas).
I had naively expected ces.nii and cespct.nii to be equivalent in this case, but in fact, cespct.nii is steeply larger and only imperfectly correlated with ces.nii. What am I missing?
