Source estimation
One advantage of the "grand-mean" approach is that you can explore a range of source estimation techniques, e.g. implemented in commercial or freeware software packages, and take advantage of their visualisation functionalities. Below this is briefly illustrated using some plots from the commercial software package CURRY (V6). Look here for more commercial software packages that are available at the CBU: http://imaging.mrc-cbu.cam.ac.uk/meg/CommercialPackages
