Galaxy... from genomic data science gateway to global community
Keynote presentation on Galaxy (https://galaxyproject.org) origins and the Galaxy community presented at Gateways 2019, the annual meeting hosted by the Science Gateways Community Institute (https://sciencegateways.org/)
biological function What is aligned to what and does it overlap with anything interesting? Can we see specific signals in alignments that inform us about specific functions? Answering these questions requires computational approaches
the production of the right protein at the right time controlled? - How are cells organized in 3D? - How are cell types decided in development? - How are different species related? - What genome variants lead to different phenotypes or disease risk?
- Large scale data acquisition has become easy, e.g. high-throughput sequencing and imaging - Experiments are increasingly complex - Making sense of results often requires mining and making connections across multiple databases - Nearly all high-profile research involves some quantitative methods How does this affect traditional research practices and outputs?

complex computational resources and methods. Can all researchers access these approaches? How can we make these methods available to everyone Transparency: Is it possible to communicate analyses and results in ways that are both easy to understand and provide all of the essential details Reproducibility: Can analyses be precisely reproduced, to facilitate rigorous validation and peer review, and ease reuse?
documents with integrated analysis Analysis environment automatically and transparently tracks details Workflow system for complex analysis, constructed explicitly or automatically
integrating a wealth of tools, compute resources, terabytes of reference data and permanent storage Open source software that makes integrating your own tools and data and customizing for your own site simple An open extensible platform for sharing tools, datatypes, workflows, ...
from the very beginning - Fortunately nobody knew about it at first, and in 2005 the data wasn’t all that big anyway - However, the demand for easy-to-use tools in the research community was even more than we anticipated… and we didn’t have much funding - For eight years Galaxy was run largely on surplus hardware decommissioned by other groups, borrowed storage, whatever we could find
of dedicated compute resources (deployed on TACC’s internal cloud) provide basic services and first line job execution - The bulk of Galaxy jobs run on Jetstream, an OpenStack cloud which allows us to leverage elasticity to efficiently adjust to changing user demands - Unique resources like Bridges and Stampede2 allow us to serve jobs that have extremely large memory demands (e.g. genome and transcriptome assembly), or are highly parallel with long runtimes (e.g. large-scale read mapping jobs)
run larger jobs, and more jobs: 325,000 jobs run on behalf of 12,000 users Can run new types of jobs: Galaxy Interactive Environments: Jupyter, RStudio (Enis Afgan)
The Galaxy Toolshed (2011) makes it easy to share those tools - However, new tools are published far faster than we can integrate them - We needed help if this is going to scale at all!
the GitHub repository. This repo serves as an excellent example and inspiration to all Galaxy tool developers. • Cultivates and shares the Galaxy tool development best practices document. • Provides support to tool developers on a public Gitter channel.
governance policy for core Galaxy code - We established the committers group, consisting of experience Galaxy developers with the responsibility of managing contributions, as well as adding additional committers - All committers have equal power – we gave up control over the code in order to share ownership with the community!
These are already distributed by CVMFS, but organized in a ad hoc manner due to the history of Galaxy - Currently building an automated approach where metadata defining the complete set of reference and index data will live in Github, builds will be automated based on Github state, and succesfull builds deployed through CVMFS for replication to all site - Intergalactic Data Commission: https://github.com/usegalaxy-eu/idc - Common tools - A common set of tools and a common tool menu organization is currently being defined. Tools and tool configuration will also be replicated through CVMFS - This will ensure both that users will have the same user experience across different usegalaxy. ✱ instances, and that workflows can be moved between instances and still execute correctly and reproducibly - Local custom tools will still be supported but clearly identified
data is greatly increased by integration across datasets - e.g. in human genomics, power to detect relationships between individual variants and disease depends on the number of individuals measured Moving/copying data is wasteful: transfer costs, redundant storage costs Human genomic data comes with privacy concerns, need to ensure security and detect threats
data to the researcher - Copying/moving data is costly - Harder to enforce security - Redundant infrastructure - Siloed compute Goal: Bring researcher to the data - Reduced redundancy and costs - Active threat detection and auditing - Greater accessibility - Elastic, shared, compute
the genomic scientific community - Cloud-based infrastructure - Shared analysis and computing environment - Support genomic data access, sharing and computing across large genomic, and genomic related, data sets - Genomic datasets, phenotypes and metadata - Large datasets generated by NHGRI programs, as well as other initiatives / agencies - Data access controls and data security - Collaborative environment for datasets and analysis workflows - ...for both users with limited computational expertise and sophisticated data scientist users
scalable analytics, data visualization 2. Organize and host key NHGRI datasets CCDG, CMG, eMERGE, and more 3. Operate services for the world Security, training & outreach, new models of data access

other protected data will only be available from a small set of analysis platforms - For the foreseeable future this is motivated by policy, compliance, and political questions rather than technical concerns - Moving data requires meeting substantial compliance requirements - Making gateway software more modular and flexible, along with standards for deployment can mitigate this - Kubernetes could be a lowest common denominator, but more standardization is needed - We need to renew emphasis on interoperability at the platform, tool, and workflow level
~315 (~39 new since last year) - Tools: contributors to galaxyproject/tools-iuc: - ~195 (~38 new since last year) - ...and the ever vigilant Intergalactic Utilities Commission for handling these contributions and maintaining the quality of essential Galaxy tools - ...and everyone else who has contributed a tool to the ToolShed - Training: contributors to galaxyproject/training-material - ~140 (~34 new since last year) - ...and everyone who has conducted or attended Galaxy Training - Everyone who has contributed to Galaxy in other ways: - users, supporters, … - Funding: NSF and NIH (to our team), and all of the funders of the Global Galaxy Community
