In this case you would have six regressors: 1. control-offset 2. hiv-offset 3. control-age 4. hiv-age 5. control-ed 6. hiv-ed If you want to test group thickness "regressing out" the effect of age and ed, then you would just set the contrast to: 1 -1 0 0 0 0 0 Note that this will test it at ag

Hi Fatima, You probably would find it easier easier to just point recon-all directly at the dicoms with -i. It saves the conversion step. If you do the conversion and put the runs in the orig dir then you don't need -i anymore, it will find them. cheers, Bruce On Wed, 17 Jun 2009, Ahmed,
