Hi,
I did a 2nd level multiple regression with two external behavioral factors as covariates upon a first level contrast. Now the Design shows me 3 columns, one for each of the covariates and one for the intercept, and I can make a contrast to look at the contribution of each covariate to the multiple regression (provided my understanding of this is correct). What I would really like to see though, is the final multiple regression model where both covariates are used together to predict the BOLD effect in my first-level contrasts across my subjects, so that for the multiple regression as a whole I can convert the t-map to an r-map with vbm afterwards.
Thanks for your help,
Dominik
