Saving Scenes and Unsaved Data

Overview

The option to save a scene and its data is accessed through the Application GUI's File menu using File->Save, or by using the Ctrl-S keyboard shortcut. The interface allows you to save the current scene (including all scene snapshots, fiducial lists, etc.) and/or individual datasets.

Note: in order to provide a rich set of options for saving data, the Save Scene and Unsaved Data interface does not behave in the way that Windows data exploerer and Gnome file browser behave. The user is encouraged to read this documentation carefully, and be mindful when specifying save options. Consider using this interface in the following three steps:

1. Select What to Save

When invoked, Slicer will select the scene and any modified datasets for saving by default. This set of selections can be overridden by manipulating the checkboxes in the leftmost column. The four icons in the panel's upper left provide convenient selection shortcuts for commonly-used selection states arrayed in the interface, from left to right:

  • Select Scene Description and Modified Data
  • Select Modified Data Only
  • Select Everything
  • Deselect Everything

Icons

2. Select Save Destinations

3. Modify Filenames & Formats

  • Make sure that you follow the following procedure:
    • specify the path to the scene file in the save scene section by clicking on the little folder icon
    • then specify the data directory by clicking on that folder icon
    • finally, you can specify the file names for the data and model files to be saved. By changing the extension, you can determine what file type will be used to save the data. .nrrd for instance will save the volumes in the nrrd format.


Save Data GUI


Note: many file formats are 'lossy' when it comes to saving and restoring metadata. For example, Analyze format cannot store all image orientations and .vtk format for images does not store orientation information at all. When exporting data to a new format, please reload the data to ensure the correct data has been saved. In general, NRRD, NIfTI, and Meta formats preserve exported information.
