Hi all,
Does anyone know how to extract average (thickness/area/GI) values of a cluster A for subjects in a group which was NOT included in the model where this cluster A emerged? For example: in a t-test for diagnosis1>dagnosis2 there is an effect in an insulacluster (found with mri_glmfit -sim); post hoc I want to test whether diagnosis1 and/or diagnosis2 differ from healthy controls in exactly the same cluster. I understand I can run the analyses in seperate models (one for diagnosis1 vs HC and one for diagnosis2 vs HC; if this cluster does not emerge in either model, there is no difference) but if I want to plot all groups for visualization purposes, I have no values for the HC. Thanks in advance, Maaike
