Thank you so much!
Okie doke. So then, for an interaction between gender x handedness x ROIsInteractionTerm (continuous), controlling for eTIV, the contrast would be the following?
[ 0 0 0 0 0.5 -0.5 -0.5 0.5 0 0 0 0]
All the best,
Fred

The method you describe is only for discrete variables, not continuous ones. The traditional method for continuous variables is to create a new variable where you multiply them together. You should normalize you continuous variables too (ie, subtract the mean and divide by the stddev).

Dear Fs support,
If I have the following FSGD with 4 classes and 3 variables, and I'd like to run an interaction of ROIa x ROIb controlling for the third covariate (eTIV), would I use the following contrast?
[0 0 0 0 0.25 -0.25 -0.25 0.25 0.25 -0.25 -0.25 0.25 0 0 0 0]
For the interaction of ROIa x ROIb x class + eTIV.
Thank you so much in advance for your help!
All the best,
Fred
