Introduction

Slicer can load a large variety of data in multiple ways. For Dicom data, please refer to the DICOM module documentation. For almost everything else (including scenes), you can use the Add Data dialog. For a listing of supported data formats see here. Please note that some of the formats listed are only partially supported.

For some of the more complicated formats (DWI in particular) it is recommended to first convert the DICOM data into the nrrd format using the DICOM to nrrd converter and then to load the nrrd file into Slicer. Many vendors are using non standard way to describe their DWI data in the DICOM headers. The DICOM to nrrd documentation contains a listing of specific formats that have been debugged and tested.

Add Sample Data

This module downloads a number of sample data sets from the internet. These data sets can be used for testing of slicer capabilities. Please refer to the Sample Data module documentation.

Add DICOM Data

Beginning with Slicer 4.0, Slicer holds DICOM data in a local data base. DICOM data can be imported from disk or retrieved from a PACS system (after proper setup). Please refer to the DICOM module documentation.

Add Data

The Add data dialog allows you to load virtually any type of data that Slicer can handle. It should be used as the default way of loading data, with the exception of DICOM, which has its own interface. Data is added to the existing scene.


"Add Data" Functionality

  • The Choose Directory to Add button adds all files inside the selected directory to the file list.
  • The Choose Files(s) to Add button adds all selected files to the file list.
  • The Show Options checkbox shows/hides the option column which controls properties assigned to an object at loading time. Here you can identify a file as a label map or a streamline.
  • The Reset button clears the entire list of files to load.
  • The Ok button loads all datasets in the list, and
  • The Cancel button aborts the entire load.

Add Volume Data

This dialog is deprecated.

The Add Volume dialog allows you to load volume files into the existing scene.

Add Volume

There are 2 Ways to Open the Add Volume Dialog

  • From the File menu

File/Add Volume

Options

At the bottom of the dialog, a list of components offer options and controls on how to load the selected volume(s)

  • Node name input box: the name (by default: filename with no extension) that refers to the volume within Slicer
  • Centered: ignore the position information from the file and center the volume on (0,0,0) instead
  • Ignore orientation: ignore the orientation information from the file and use the Identity instead
  • LabelMap: flag the volume as a labelmap, it will behave differently by default (no linear interpolation, use a lut…). By default, files containing the word “seg” are automatically flagged as LabelMap.
  • Single File: control whether the volume is defined within one or multiple files. For example a stack of 2D image files to make a 3D volume. This is usually the case with DICOM files. When a volume is made of multiple files, select only the first file and uncheck the Single File checkbox.

Uncheck Single File when volume is within multiple files

Favorites

When searching for files, in order to quickly find your data, it is possible to use favorites, symbolic links saved and restored for each session.

Favorites in file dialog

To create a symbolic link, you drag&drop a directory from the right panel to the left panel. It will be remembered next time you start slicer.

Drag and drop to add a new Favorite
