RE: Converting first-level ROI-to-ROI files
Hi Roger,
Yes, the transformation is rather simple (hyperbolic tangent function, or tanh in Matlab). For example:
r_Pearson = tanh(r_Fisher);
r_Fisher = atanh(r_Pearson);
Hope this helps

Hi all,
Is it possible to convert the first level ROI-to-ROI correlation matrices from Fisher's z to Pearson r? Any insight would be appreciated.
