MRML:The Medical Reality Markup Language (MRML) scene file is an XML-based text file that references all data loaded into Slicer, and records its display and processing parameterization. Loading a MRML scene file will also load its referenced data and display it in the manner it was saved.

| File->Load Scene: This load command selected from Slicer's File Menu will close the current scene, pop up a File Browser, and load data from the MRML scene file you select. File->Import Scene: This load command selected from Slicer's File Menu will pop up a File Browser, and add all data referenced in the MRML scene file you select into the current scene. File->Load Volumes: Select that option to load individual volumes or to use the DICOM browser. File->Add Data: Raise a load panel with a set of options for loading individual datasets or entire directories containing data. File->Add Transform: provides an option to load a transformation matrix.
| Load or Import Scenes or Data: Clicking the Load icon (shown at the left) from Slicer's Toolbar exposes the options to Load or Import a MRML scene, or to raise the "Load Data" panel to select individual datasets or entire data directories.
| Load Any: Find a convenient collection of options to load scenes and all supported data types in the "Data Module's", Load & Add Scenes or Individual Datasets Panel. The "Data Module" can be accessed using its icon (shown at the left) in Slicer's toolbar, or by using the Modules Menu. Once data has been added to the scene, it will be displayed in the "Data Module's" data tree.
