Abstract
We consider signal estimation for functional MRI studies on multiple subjects. There are two major issues; alignment or registration of images across subjects, and using the multisubject information to capture covariance information; we discuss only the latter. Capturing this covariance information properly can lead to great improvements in statistical efficiency beyond what simple averaging can offer as well as compact description of group features
