I have two group of subjects.For each subject. I take two scans for each subject with two condition. Then I do the 3dTcorrelation for this two scan within each one subject. So I get the correlation coefficient for each voxel for each subject. The value of the correlation coefficient is range from -1 to 1.
Now, I want to do the 3dttest++ for the two group of subjects. I want to know if I need to do the fisher-z translate for the correlation coefficient.
