Is there any instruction to analyze correlation between cortical thickness

On the misuse of residuals in ecology: regression of residuals vs. multiple
regression
1. Robert P.
Dear all,
I've a question regarding computing correlations with cortical thicknesses
on the surface; Suppose I have two variables for each subject: (age and
weight) and I want to compute the correlation between cortical thickness
and weight, corrected for age.
Option 1:
Fsgd contains: Variables
In the 2nd option, age and weight (and other variables) are
simultaneously fit to the data. Most people refer to this as regressing
out the effect of one variable when looking at the other. But it is not
regressing out age and then looking at the correlation of age with the
residual.
