Hi Doug, I have used fscalc to create subject-level Z score maps of cortical thickness against a set of healthy controls.
fscalc $i/surf/lh.fsaverage.mgh sub group_mean_control_lh.mgh div group_std_control_lh.mgh --o $i/surf/lh.Z.thickness.fsaverage.mgh; done Beyond this, is there a way to adjust the Z score maps for age, and then produce an age-adjusted Z score map? Thanks for your help.
