Hi Gang,
Thank for your answer!
The subjects were not measured exactly at the same age but within the same session. The effect of interest is the age and I am looking to observe a correlation with the modification of the connectivity strength. As an example, I previously did an extraction of the ALLF signal with an atlas and then calculated the Repeated measures correlation coefficient within each cerebral region.

I don't know what is the best way to do it for a voxel-wise approach. For now, I had only one explanatory variable but finding a test that could allow me to add some if needed or to change the effect of interest (I will have behavioral and other biological data) would be great.
Thank you so much for your help!
Clément
