degrees of freedom
Hello
I'm writing only about single-subject analyses here.
You proposed in 2014 a piece of code for comparing the two r maps from two ROI-Voxel conditions. This code takes two BETA maps, containing Fisher transformed r values, and computes p and pFDR maps. Apparently, it uses the DOF (in my case 117) indicated in the Denoising panel as "before denoising". Why doesn't it use the DOF "after denoising" (in my case 54)? I'm asking because I made a couple of scripts using the "after denoising" DOF and I'd like to know if/why I'm wrong...
Tnak you very much in advance
Laurent
