Please note that Slicer continues to be a research package and is not intended for clinical use. Testing of functionality is an ongoing activity with high priority, however, some features of Slicer4 are not fully tested.
The Slicer Training page provides a series of courses for learning how to use Slicer4. The portfolio contains self-guided presentation and sample data sets.

The main slicer.org pages provide a guided tour to the application, training materials, and the development community. New users should start there because we try to keep the pages organized and up to date.
