OpenStructure - A computational structural biology framework

OpenStructure provides a modular, flexible, molecular modelling environment which allows to integrate, process and visualize information of different origin such as sequences, alignments and 3D structures.

Please refer to www.openstructure.org for more information and documentation.

Thank you for your interest and enjoy the straightforward way of handling protein structure data!

OpenStructure Installation

For a simple and portable setup, we recommend using a containerized solution. OpenStructure provides its own Docker container registry, making deployment easier. Deploying a docker image just needs a docker pull which typically finishes in about a minute depending on your local hardware and internet connection. Singularity containers bootstrap from the docker container but must be built by the user.

Docker

For complete documentation on using Docker with OpenStructure, click here. This section provides a quick-start guide to help you get OpenStructure up and running using Docker. Most docker installations require you to add sudo in front of the docker commands.

Get the latest Docker image from the OpenStructure registry:

docker pull registry.scicore.unibas.ch/schwede/openstructure:latest

And run a test script:

echo print\(\"Hello OST\"\) > test.py
docker run --rm -v $(pwd):/home registry.scicore.unibas.ch/schwede/openstructure:latest test.py

Singularity

For complete documentation on using Singularity with OpenStructure, click here. This section provides a quick-start guide to help you get OpenStructure up and running using Singularity.

Building the singularity container requires root permissions:

wget https://git.scicore.unibas.ch/schwede/openstructure/-/raw/master/singularity/Singularity
sudo singularity build ost.img Singularity

And run a test script:

echo print\(\"Hello OST\"\) > test.py
singularity run --app OST ost.img test.py

Build from source

OpenStructure is developed and tested across various Linux distributions. You can find detailed build instructions and a list of required dependencies in the online documentation.

Getting started

Once you have OpenStructure installed, check out the online documentation.

Additionally, here are some advanced use cases worth highlighting.

Benchmarking and Scoring

OpenStructure implements a benchmarking suite for comparing macromolecular complexes. To get started, check out the examples in the examples/scoring directory of this repository.

Modeling

ProMod3 is a fully featured modeling engine built on top of OpenStructure. It powers the SWISS-MODEL web server and provides advanced modeling capabilities. Learn more here:
