RuSirius

Project Status: Active – The project has reached a stable, usable state and is being actively developed.

RuSirius (spelled R-U-Sirius (are you serious)) is an R package that provides an interface to the Sirius software, enabling seamless integration of xcms preprocessing results with Sirius.
It is built upon RSirius, the REST API library for the R programming language, which you can find here.

Installation Instructions

Option 1: Install Sirius and R-api via Conda

  1. You can install both the Sirius software and the R API using conda with the following command:
conda create -n sirius conda-forge::r-sirius-ms
conda activate sirius
  1. Then, in an R session, install RuSirius and it’s dependencies :
library(remotes)
install_github("RforMassSpectrometry/RuSirius")

Alternatively, you can manually install Sirius and then RuSirius:

  1. Download the Sirius software from the official releases page. RuSirius is dependent on Sirius 6.3, please ensure you have the right version downloaded.
  2. Install RuSirius and it’s dependencies (which includes the R-api) by running the following code in R:
library(remotes)
install_github("RforMassSpectrometry/RuSirius")

Usage

RuSirius comes with five vignettes to help you get started:

  1. Getting Started with RuSirius This vignette covers the basics of connecting to Sirius and managing projects.

  2. Importing Spectra into Sirius This vignette shows a basic example for importing spectra data into Sirius.

  3. Retrieving Results from Sirius This vignette explains how to retrieve and interpret different result types.

  4. Using Custom Databases This vignette demonstrates how to create and use custom databases for structure search.

  5. Importing Chromatographic Peaks from xcms This vignette demonstrates how to import chromatographic peaks from xcms and use them in Sirius.

Contributing

We welcome contributions and bug reports! If you encounter issues, have suggestions, or want to contribute code, please open an issue or pull request on the GitHub repository.

Before submitting a PR, please ensure:

  1. Tests pass locally: Run tests one file at a time to avoid API conflicts. Running all tests together with devtools::test() can cause SIRIUS startup issues due to port conflicts:

    testthat::test_file("tests/testthat/test-api-responses.R")
testthat::test_file("tests/testthat/test-helpers.R")
testthat::test_file("tests/testthat/test-import-helpers.R")
testthat::test_file("tests/testthat/test-input-validation.R")
testthat::test_file("tests/testthat/test-integration.R")
testthat::test_file("tests/testthat/test-msn-import.R")
testthat::test_file("tests/testthat/test-param-classes.R")

  2. Pre-rendered vignettes are up to date: All five vignettes are pre-rendered from .Rmd.orig sources. If your changes affect package output or vignette content, re-run the pre-render script from the package root with Sirius running on port 9999:

    source("vignettes/pre-render.R")

    Commit the updated .Rmd files alongside your changes.

Note that CI runs R CMD check with --no-vignettes since vignettes require a running Sirius instance with authentication.

## Known Issues
### Current Issues:
- Vignettes require Sirius login: Vignettes cannot be built automatically in CI as they require Sirius authentication. Pre-rendered vignettes are available on the pkgdown site.
- Importing features can be time-consuming. To speed up testing, import only a few features at first and limit the process to one MS1 spectrum per feature. Further details are provided in the vignettes.

Docker

A pre-built Docker image is available on Docker Hub, based on the official Bioconductor docker image bioconductor/bioconductor_docker:RELEASE_3_22. It includes RuSirius, all dependencies, and Sirius 6.3.3 (downloaded directly from the official GitHub releases). The Sirius REST API starts automatically on port 9999 when the container launches.

Pulling the image 

docker pull rformassspectrometry/rusirius:latest

Running the container

Start an RStudio Server session:

docker run -e PASSWORD=yourpassword -p 8787:8787 rformassspectrometry/rusirius:latest

Then open RStudio Server at http://localhost:8787 (user: rstudio, password: as set above).

Or start an interactive R session directly:

docker run -it rformassspectrometry/rusirius:latest R

Sirius login

Sirius starts automatically inside the container on port 9999. Connect and log in from the R console:

library(RuSirius)
srs <- Sirius(projectId = "my_project",
              username = "your_email",
              password = "your_password",
              port = 9999)

Note that Sirius requires a valid account — you can register for free at https://bright-giant.com.

Building the image locally (advanced)

If you prefer to build the image from source instead of pulling from Docker Hub:

docker build -t rformassspectrometry/rusirius .

This builds the image using the Dockerfile in the repository root.

Thanks

Many many thanks to Markus Fleischauer for his work on the Sirius SDKs, many more Jonas Emmert who made the R-API usable. And Marcus Ludwig for the help and support in implementing RuSirius.
