Overview

Back to Table of Contents

CoLlAGe captures subtle anisotropic differences in disease pathologies by measuring entropy of co-occurrences of voxel-level gradient orientations on imaging computed within a local neighborhood.

CoLlAGe is based on the hypothesis that disruption in tissue microarchitecture can be quantified on imaging by measuring the disorder in voxel-wise gradient orientations. CoLlAGe involves assigning every image voxel a ‘disorder value’ associated with the co-occurrence matrix of gradient orientations computed around every voxel.

Details on extraction of CoLlAGe features are included in [1]. After feature extraction, the subsequent distribution or different statistics such as mean, median, variance etc can be computed and used in conjunction with a machine learning classifier to distinguish similar appearing pathologies. The feasibility of CoLlAGe in distinguishing cancer from treatment confounders/benign conditions and characterizing molecular subtypes of cancers has been demonstrated in the context of multiple challenging clinical problems.

Code

Idempotence

Back to Table of Contents

Our CoLlAGe module includes parameter tuning information in the output. It contains the image(s) and mask(s), and the settings applied upon them. This allows multiple fully reproducible runs without having to remember or find the original parameters.

Dependencies:

Back to Table of Contents

We thank these generous developers that allowed us to build collageradiomics without reinventing the wheel:

• matplotlib
• numpy
• scikit-learn
• scikit-build
• mahotas
• scipy

(Note: We are using == for version numbers of our dependencies as a design choice.)

Installation & Usage

These instructions will help set up the CoLlAGe core module and examples. They assume you are working out of a terminal such as Powershell on Windows or Konsole on Linux.

Executive Summary for Experts

If you are already well-versed in Docker and pip, here is a quick list of commands for each operating system:

Linux

sudo docker pull radxtools/collageradiomics-pip:latest
sudo docker run -it radxtools/collageradiomics-pip

git clone https://github.com/radxtools/collageradiomics.git
sudo docker pull radxtools/collageradiomics-examples:latest
sudo docker run -it -p 8888:8888 -v $PWD:/root radxtools/collageradiomics-examples

pip3 install collageradiomics

Windows

docker pull radxtools/collageradiomics-pip:latest
docker run -it -v ${PWD}:/root radxtools/collageradiomics-pip

git clone https://github.com/radxtools/collageradiomics.git
docker pull radxtools/collageradiomics-examples:latest
docker run -it -p 8888:8888 -v ${PWD}:/root radxtools/collageradiomics-examples

pip install collageradiomics

You may wish to jump right to some Python examples.

Docker

Back to Table of Contents

Docker is like a stand-alone operating system container that comes pre-installed with all the dependencies already set up properly. It allows you to jump right into coding with CoLlAGe. We offer 2 Docker images: a basic core image for you to start coding with the CoLlAGe features (called collageradiomics-pip) and an image that contains a running Jupyter notebook with CoLlAGe pre-installed and examples ready to run (called collageradiomics-examples).

collageradiomics-examples Docker Image

Back to Table of Contents

This Docker image contains a running Jupyter notebook with the CoLlAGe module pre-installed. From the cloned repository directory, we will start up a Docker image which will run a live web server and host a Jupyter notebook at the URL http://localhost:8888 which contains examples of using the code.

Note: Using this method requires you to pull the code from our repository. If you don't need the Jupyter examples and just want to start using CoLlAGe right away, you can skip this step and jump to the instructions for Core by clicking here.

If your terminal prompt changes to root@[random_string]:/# then you are now working inside the standardized Docker sandbox container environment.

1. Test the python module by making sure the following command outputs True to the terminal:

PS C:\Users\user> python

Could not import submodules (exact error was: DLL load failed while importing _bbox: The specified module could not be found.).

There are many reasons for this error the most common one is that you have
either not built the packages or have built (using `python setup.py build`) or
installed them (using `python setup.py install`) and then proceeded to test
mahotas **without changing the current directory**.

Try installing and then changing to another directory before importing mahotas.
