you're fsgd includes age, so it should account for differences in age in your groups
The cluster formation does not use any information about the thickness or age directly. It strictly uses the voxel-wise p-values. doug Antonella Kis wrote: > > > > Dear All, > > When I designed the matrix consisted of two discrete groups, > (patients vs. controls), > I choose age as a covariate so during my analysis I was lookingif > there is a difference in the cortical thickness within patients > versus controls while accounting for age. > Should I change my FSGD in order to be able to compare between > patients and controls accounting for age (I want to make sure that the > age does not confound my results).
