COLlAGe is available as a prebuilt Slicer extension for Windows only (macOS/Linux in progress):

Instructions (as of 19 Nov 2018, for Slicer v4.11):

  1. Please download the latest nightly build version (*** Version 4.11.0**) of 3D slice r here:
  2. Download the latest release ZIP file from GitHub (containing the prebuilt CoLlAGe extension):
  3. Extract the contents of to any temporary local folder on your computer.
  4. Within this extracted folder:
    • Copy the contents in [^extracted folder]\lib\Slicer-4.11\cli-modules to C:\Program Files\Slicer 4.11.0-2018-11-16\lib\Slicer-4.11\cli-modules
    • Restart 3D Slicer
  5. Find the installed plugin bly clicking Modules -> COLlAGE Texture Radiomics

Note that just trying to load the ZIP file into Slicer does not appear to work consistently, the above steps have been tested by us as an alternative.

The source code is also available, under an Apache 2.0 license.

Instructions for building COLlAGe from this source code is available on the wiki for this plugin.

Fully compiled command line executables for Unix and Windows are also available (including sample data):

Usage for CLI executable:

../CollageFeatureExtractor2D.exe “inImage.mha” “inMask.mha” 2 “outImage.mha”

CLI executable takes the following 4 inputs:

  • Input Arg. 1: Input Greyscale, meta Image, MR Image (.mha format or ITK compatible)
  • Input Arg. 2: Input Binary, meta Image, Tumor label (.mha format or ITK compatible)
  • Input Arg. 3: Neighborhood Radius (integer)
  • Input Arg. 4: Output feature map, meta image path
