Colm,

Use RBA instead of BayesianGroupAna.py for region-based analysis since I've been maintaining and adding more functionalities into RBA.

Currently RBA allows for between-subject (categorical and quantitative) variables as predictors. I'll try to add the functionality of modeling within-subject variables soon.

Sure. Basically if you have a GLM under the conventional framework, you can use RBA. I'll try to expand its modeling capability to the case with repeated-measures variables.

Thanks for catching the mistakes there!
