Overview

Slicer offers a variety of predefined lookup tables (LUT). Volumes can be associated with a LUT in the volumes module. Also, see the Colors Module.

LUTs in Slicer

You can review and edit LUTs in Slicer via the Colors module.

Slicer ColorPicker

The slicer colorpicker allows to select colors from a label map and to assign them to objects such as surface models or streamlines.

Custom LUTs

It is relatively easy to create custom LUTs by creating a table with the colors on the wiki. This allows to select specific names and colors when segmenting. See below for an example.

integer_label	text_label	color	notes
0	background	rgba(0,0,0,0)
1	tissue	rgb(128,174,128)	Default label for bodily tissues
2	bone	rgb(241,214,145)
3	skin	rgb(177,122,101)
4	connective tissue	rgb(111,184,210)

• Standard color names and values: http://www.w3.org/TR/SVG/types.html#ColorKeywords
• Go here to create a text file in Slicer LUT format.
• A custom LUT can be loaded into Slicer like any other file.

Custom LUT Examples

• Mori-Atlas labels
• Lauras labels
• 2010 Brain Atlas: Good example of the wiki-based labelpage format, including multiple tables.
• TractographyColors LUT for WM parcellation.
