not sure if this has already been reported, but if I save a session in which I have imported IMOD models (surface meshes + contours), and then reload the session, only the contours appear - the surface meshes do not. this is using build 2416, May 30 2007 release. -Jeff -- ------------------------------------------------------------- Jeff Triffo Auer Group, Donner Lab, Lawrence Berkeley National Laboratory Raphael Group, Bioengineering Department, Rice University Medical Scientist Training Program (MSTP), Baylor College of Medicine phone (Berkeley): 510-486-7940 fax (Berkeley): 510-486-6488
