hi.
I have a few questions about the z-matrix that came from the 2-nd analysis of ROI to ROI.

1. why is the matrix came in Z-values and not r (Pearson)?
2. how can I extract a matrix with only my ROIs and not all the ROIs (167).
3. how can I find the coefficient values for each z in the matrix?
4. Is there any transformation between the Z-values and t / betas values?

Thank you very much.
Sandy.
