Running HippUnfold with a Vagrant VM

This option uses Vagrant to create a virtual machine that has Linux and Singularity installed. This allows you to use Singularity to run HippUnfold from a clean environment, whether you are running Linux, Mac or Windows (since all three are supported by Vagrant). Note: VirtualBox does the actual virtualization in this example, but Vagrant provides an easy and reproducible way to create and connect to the VMs (as shown below).

Install VirtualBox and Vagrant

The example below uses Vagrant and VirtualBox installed on Ubuntu 20.04.

The Vagrant install instructions describe what you need to do to install on Mac, Windows or Linux.

Vagrant must use a provider for the actual virtualization. The instructions here assume you are using VirtualBox for this, since it is free and easy to use, but in principle should work with any virtualization provider. The VirtualBox downloads page can guide you through the process of installing it on your system (Mac, Windows, Linux supported).

Create a Vagrant Box

Once you have Vagrant and VirtualBox installed, the following screencast demonstrates how you can setup a Box with Singularity pre-loaded on it. The main steps are to 1) create a Vagrantfile, 2) start the box using vagrant up, and 3) connect to it using vagrant ssh.

Note: These screencasts are more than just videos, they are asciinema recordings – you can pause them and then copy-paste text directly from the asciinema cast!

This is the Vagrantfile used in the video, for quick reference:

Vagrant.configure("2") do |config| = "sylabs/singularity-3.7-ubuntu-bionic64"
  config.vm.provider "virtualbox" do |vb|
     vb.cpus = 8
     vb.memory = "8096"

Download the test dataset

We are downloading the test dataset with the following command:


Download the HippUnfold container

We download the Singularity container for HippUnfold using Dropbox in this example:


Note, you can also pull/build the container from DockerHub:

singularity pull docker://khanlab/hippunfold:v1.2.0
