Dear FreeSurfers,
I am interested in examining interaction effects between two sets of classes where each covers all the data, let's say Male/Female and Treatment/Control. I know mri_glmfit can be used to run t-test comparisons between groups (e.g. All Treatment vs. All Control , or Male & Control vs. Male & Treatment), but can mri_glmfit be used to examine interaction effects between these two sets of classes (for surface data)?
my FSGD file looks like this: GroupDescriptorFile 1 Class MaleTreatment Class MaleControl Class FemaleTreatment Class FemaleControl Input subjid1a MaleTreatment Input subjid1b FemaleTreatment Input subjid2a FemaleControl Input subjid2b MaleControl etc...
Thanks, Sasha
