The encoding of the coordinate system is independent of it being well centered. \r\n\r\nAlso, when I'm writing about \"centered\", it's always with respect to the visualisation in trackvis. What i have observed is that the volume and the tracts are always coordinated, just off the rotation center of the interface. \r\n\r\nSo any post-processing tool for stats or information extraction, such as my tract_math tool, included in the package, should output the good numbers. \r\n\r\nDemian"}}
