# Science
## Overview
_[Back to **Table of Contents**](#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 [\[1\]](#references). 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.

## Features
_[Back to **Table of Contents**](#table-of-contents)_

Each of the 13 **CoLlAGe** correlate to one of the 13 Haralick texture features[\[2\]](#references):

# Code

## Idempotence
_[Back to **Table of Contents**](#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.

## Documentation
_[Back to **Table of Contents**](#table-of-contents)_

http://collageradiomics.rtfd.io/

## Dependencies:
_[Back to **Table of Contents**](#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
_[Back to **Table of Contents**](#table-of-contents)_

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

### Linux
```shell
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
```console
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](https://github.com/radxtools/tree/master/jupyter/examples).

## Docker
_[Back to **Table of Contents**](#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](#collageradiomics-pip-docker-image)_) 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)_).

### collageradiomics-examples Docker Image
_[Back to **Table of Contents**](#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](#collageradiomics-pip-docker-image)._

### collageradiomics-pip Docker Image
_[Back to **Table of Contents**](#table-of-contents)_

This is the most straightforward way to start playing with the code. And it does not require the `git` commands that the **Jupyter** examples require. This is simply a pre-built container that lets you start trying out the module in **Python** immediately.

#### Inside The Container
_[Back to **Table of Contents**](#table-of-contents)_

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:  
```console
root@12b12d2bff59:/# python -c 'import numpy as np; import collageradiomics; print(not not len(collageradiomics.__name__) and not not len(collageradiomics.Collage.from_rectangle(np.random.rand(20,20,3), 2, 2, 10, 10).execute()));'
True
root@12b12d2bff59:/# 
```
2. Starting coding with **CoLlAGe** in **Python** [(click here to jump to code examples)](#python-usage):
```console
root@12b12d2bff59:/# python

Type "help", "copyright", "credits" or "license" for more information.
>>> import collageradiomics
>>> collageradiomics.__name__

```
3. Exit the **Docker** container:
```console
>>> quit()
root@12b12d2bff59:/# exit
exit
```

Try the new cross-platform PowerShell https://aka.ms/pscore6

PS C:\Users\user> python
>>> import collageradiomics

6. If you get an error like the one below, which can happen for some versions of python, call `import` again:
```console
Windows PowerShell
Copyright (C) Microsoft Corporation. All rights reserved.

Try the new cross-platform PowerShell https://aka.ms/pscore6

PS C:\Users\user> python
>>> import collageradiomics
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.
>>> import collageradiomics
>>>
