Hi Martin, Thank you. How should this variable be coded ? Should it be as age covariate where age at baseline is used along all time points of each subject ?
Could you provide me an example of design matrix, I don't manage to see what does it look like to.

Instead of group, you use a variable for your score (and interaction etc). Sometimes it may also makes sense to use score instead of time.

As it is possible to test for interaction of group X time, is this also in the same way feasible to test for coognition score X time on cortical thickness ? > > Many thanks for your advice ! > > Best regards, > Matthieu > _______________________________________________ > Freesurfer mailing list > Freesurfer@nmr.mgh.harvard.edu > https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.
