Dear FS team, Thank you very much for your help. Just a few more questions.
I want to perform a statistical analysis between two groups:controls and patients, using age and IQ as covariates. First I have to test if there is an interaction between group and covariate using DODS. My questions are: Q1) Do I have to test age and IQ separately, or together? Q2) In case that there is not interaction in any of the covariates, can I use the same FSGD file but do I have tu run it as DOSS? How it could be done? I would appreciate if you could give me some hints or examples about the matrices and contrast files that I must use. Thank you, All the best, Laura _______________________________________________ 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.
