There are a couple of things you can do. To get info on the coordinate systems, look at the power points slides we have on the wiki (search for coordinates). The other thing you can do is to sample your functional data onto the surface and then load that into matlab. Then each anatomical vertex will have a corresponding functional data point and you don't need to do the transform yourself.
