Welcome to the world of Single Cell Omics

{:.no_toc}

The Single Cell Omics workbench is a comprehensive set of analysis tools and consolidated workflows. The workbench is based on the Galaxy framework{:target="_blank"}, which guarantees simple access, easy extension, flexible adaption to personal and security needs, and sophisticated analyses independent of command-line knowledge.

The current implementation comprises more than 20 bioinformatics tools dedicated to different research areas of single cell biology.

This service is a joint project between different groups from the Earlham Institute{:target="_blank"}, the EMBL-EBI{:target="_blank"}, EMBL{:target="_blank"} the Sorbonne University{:target="_blank"}, Peter MacCallum Cancer Centre{:target="_blank"} and the University of Freiburg{:target="_blank"}. The server is part if the European Galaxy server and is maintained by the RNA Bioinformatics Center (RBC){:target="_blank"} as part of de.NBI{:target="_blank"} and ELIXIR{:target="_blank"}.

Get started

Are you new to Galaxy, or returning after a long time, and looking for help to get started? Take [a guided tour]({{ page.website }}/tours/core.galaxy_ui){:target="_blank"} through Galaxy's user interface.

Training

Want to learn more about single cell analyses? Check out the following hands-on tutorials from the Galaxy Training Network{:target=_"blank"}.

We are passionate about training. So we are working in close collaboration with the Galaxy Training Network (GTN){:target="_blank"} to develop training materials of data analyses based on Galaxy {% cite batut2017community %}. These materials hosted on the GTN GitHub repository are available online at https://training.galaxyproject.org{:target="_blank"}.
