Hi Aurely, I don't understand why it doesn't work when you use the Brainvisa "Roi Drawing" process. I've just tested it, it works well. Maybe you could send a screen copy of what you've done... Anyway, you can draw ROI directly with Anatomist. If you follow the steps described in Anatomist...

Hi Josselin, Currently, we are developping Brainvisa mainly on Mandriva 2008. But our system is planned to be upgraded to Mandriva 2010.
