Dear spmers,
In a VBM study I have three groups, Controls, Patients1 and Patients2, and two
numerical variables. Each subject has one pre-treatment and other post-
treatment scans. I need some help about how to do the following statistical
tests with SPM2 :
A) How to check where variations between pre and post are related with
numerical variables. I haven't found the way to introduce covariables with a
paired t-test
B) How to find if there are significant differences between pre-post variation
between groups.
Any help would be wellcome. Thanks for your attention
Yours
