Two bugs to watch out for in version 0.90: (1) When ray tracing on a light background with antialiasing enabled, a one pixel wide border may appear. To workaround this, either crop your image after saving using something like Photoshop, or simply don't antialias (just "ray" with dimensions 2X as large). Thanks to David Chimento for finding this one!
(2) Sessions containing "isosurface"-generated surfaces may not be saveable due to a Python exception. There is no workaround for this in the current version. Both bugs have been fixed in the development version under CVS. Cheers, Warren PS. Today I also added support for InsightII's ascii/formatted grid file (just in case anyone has some old Biosym GRD files lying around...). -- mailto:war...@delanoscientific.com Warren L.
