Saving a scene in VRML is limited to SR objects, and may create huge files. A more flexible alternative is to save a description of the P3D rendering in a protocol file using the Save Protocol button in the status line. When such a P3D protocol is loaded again, a dialog window appears which indicates the data to be loaded.
If the user wants to apply the same rendering to similar data, he can replace the input files with the 
buttons. Execute the protocol with Run Protocol.
Normally the scene will be cleared and replaced by the result of the protocol. To create high definition VR objects the Use Volume HD option should be enabled.
The 
button shows a dialog window containing standard rendering definitions.
Currently, the following predefined protocols are supported:
1.Heart Atlas
2.MR-AAL
3.Angio CT renderings are offered with and without multi-modal fusion.
4.Bones (CT)
5.AAL VOI
6.Mouse (CT+NM)
Note that when a predefined protocol is selected, appropriate input files have to be set using the buttons with the Load data and run protocol radio button enabled:
To apply the procedure to data already loaded, enable the Run protocol on current data radio button.
