Hi Gang,
Thanks for your response!
To answer your final question, yes, a 2D scatterplot would be nice with cytokine levels on the x-axis and corrected neural inflammation on the y-axis where "corrected" in this case means the residuals of the neural-inflammation variable after accounting for relations between the motion and VBM_Jacobian covariates. Wondering if you could specify a way, probably with 3dcalc, to use the data that went into 3dttest++ and the output of 3dttest++ to accomplish this?
Many thanks, again,
Paul
