Question about output of xcp_d

#1

Hi all,

I want to make sure that does the xcp_d do the standardization of the connectivity matrices and resting-state derivatives by Fisher r-to-Z transformations? If I need to perform some group-analyses, I would standardize the output functional connectivity and derivatives first, right?

Thank you!

Best,
Jun

Hi Jun,

xcp_d outputs the Pearson correlation coefficients. You’ll need to do the r-to-z transform yourself (e.g., with numpy.arctanh). I agree that that is probably a good first step before any group-level analyses.

Best,
Taylor
