hi
When we run a dual regression, at the 2nd stage of the analysis, we get images that are named, dr_stage2_ic_00xx.nii.gz.
We are averaging the non-zero voxels within this images for each participant to get a value for the mean connectivity score or coherence for that component.
The range of these scores in one of our samples is normally distributed about 0, with most values lying between -50 and 50.
I expected these values to lie between -1 and 1 or 0 and 1.
What normalization or shift has been applied to the values
Thank you.
