Dear conn experts,

I'm having some trouble interpreting the effect sizes in the ROI-to-ROI results. To get an overview, I've been extracting the ROI-to-ROI matrix in terms of two-tailed T-values or as beta-values.

Do the beta values still represent Z-transformed Pearson correlation coefficients in the second-level results, and how are they to be interpreted?

Is it possible to extract a ROI-to-ROI matrix with correlation coefficients ranging from -1 to 1?


Best wishes

Andreas
