FuncTree 2

MIT License

FuncTree is a web application that allows users to map omics data onto a pre-defined radial tree (e.g. based on the KEGG brite functional hierarchy) to help them quickly and comprehensively understand the functional potential of their data, and to develop further hypothesis and scientific insights.


Clone this repository and change directory to functree-ng:

$ git clone --recursive
$ cd functree-ng

Building and running the application

Using Docker and Docker Compose (preferred and supported way)

Execute the command below. docker-compose will automatically set up Docker containers:

$ docker-compose build
$ docker-compose up

Then open http://localhost:8080 in your web browser.

Automatic transpilation, for dev mode only (optional)

To enable automatic transpilation of ECMAScript and SCSS in dev mode, enter the docker instance

docker exec -it functree-ng_app_1 /bin/bash

then issue the following commands

yarn babel:watch
yarn sass:watch

Manual installation (unsupported, use at your own risk)

  • Python 3
  • Node.js
  • MongoDB

Install dependencies and build the application:

$ pip3 install -r requirements.txt
$ npm install yarn --global
$ yarn run install-depends
$ yarn run install-devDepends
$ yarn run bower install
$ yarn run build

Start up the application:

$ uwsgi --ini uwsgi.ini

Then open http://localhost:8080 in your web browser.


To configure the behavior of the application, create instance/ with the same format as functree/

Loading of functional annotations from external sources (optional)

  1. Download and edit LIST_HOME to match the location of your local KEGG distribution.
  2. Run the script to generate the file.
  3. Add to /app/functree/static/data/ortholog_mapping/ (See the docker-compose.yml services:app:volumes for details)
  4. Log into the admin console (e.g. http://localhost:8080/admin), then click the 'Update annotation mapping' link.
