Hi All, I am getting errors when trying to run a general linear model on 101 subjects looking at the effect of a continuous variable, age. In the past I've always compared groups, but now when I create a design matrix with just age and a couple other covariates, I get an error when trying to create the glassbrain. I go to results, create a new T-contrast, but when it asks for the family-wise error, the calculation never completes and I get an error. I am completely stumped. I've even tried to test between groups and it won't work anymore. Does anyone have any tips in analyzing a continuous variable? Thanks so much.
