As additional capabilities were added to the software platform, it was eventually split into several themed Workbenches and plugins with collections of features relevant to different applications (e.g. pathway analysis, genomics, and other omics). Features include read mapping and de novo assembly of high-throughput sequencing data, whole-genome detection of SNPs and structural variations, ChIP-seq, RNA-Seq, small RNA analysis, genome finishing, microbial genomics, structural biology, and functions to analyze, visualize, and compare genomic, transcriptomic, and epigenomic data.
My job is for genotyping of enteroviruses from patients. As you may know, there are lots of subtypes of enteroviruses, so we use multiple fasta references to align with fastq files. When we used your galaxy tools, like bowtie2, BWA, etc., only very few reads aligned to the multi-fasta references, but with CLC genomics workbench, lots of reads found to align to the multi-fasta references.

Analyzing high throughput genomics data is a complex and compute intensive task, generally requiring numerous software tools and large reference data sets, tied together in successive stages of data transformation and visualisation. A computational platform enabling best practice genomics analysis ideally meets a number of requirements, including: a wide range of analysis and visualisation tools, closely linked to large user and reference data sets; workflow platform(s) enabling accessible, reproducible, portable analyses, through a flexible set of interfaces; highly available, scalable computational resources; and flexibility and versatility in the use of these resources to meet demands and expertise of a variety of users. Access to an appropriate computational platform can be a significant barrier to researchers, as establishing such a platform requires a large upfront investment in hardware, experience, and expertise.
However, the reality is that the necessary tools, platforms and data services for best practice genomics are generally complicated to install and customize, require significant computational and storage resources, and typically involve a high level of ongoing maintenance to keep the software, data and hardware up-to-date. It is also the case that a single workflow platform, however comprehensive, is rarely sufficient for all the steps of a real-world analysis. This is because analyses often involve analyst decisions based on feedback from visualisation and evaluation of processing steps, requiring a combination of various analysis, data-munging and visualisation tools to carry out an end-to-end analysis. This in turn requires expertise in software development, system administration, hardware and networking, as well as access to hardware resources, all of which can be a barrier for widespread adoption of genomics by domain researchers.
We argue that lack of widespread access to an appropriate environment for conducting best-practice analysis is a significant obstruction to reproducible, high quality research in the genomics community; and further, transitioning from training to practice places non-trivial technical and conceptual demands on researchers. Public analysis platforms, such as Galaxy, provide solutions to some of these issues (particularly accessibility), but are generally handicapped by rapid growth in per-user demand for compute resources and data storage, and the enforced constraints on flexibility that are a requirement of a centrally managed resource.
Reproducible genomics requires, at a minimum, a way of accessing the same tools and reference datasets used in an analysis, combined with a comprehensive record of the steps taken in that analysis in the form of a workflow, in sufficient detail to reliably produce the same outcome from the same input data, assuming a deterministic analysis [18]. At the most basic level reproducibility can be achieved with shell scripting and documentation, but issues in ease of use, maintenance and genuine reproducibility are well-known [19], [20]. This has catalysed a number of efforts in developing platforms for reproducible scientific analysis through structured workflows, including Galaxy, Yabi, Chipster, GenePattern and numerous commercial products (e.g., Igor [21], BaseSpace ( ), Globus Genomics [22]). An environment supporting reproducible genomics requires at least a workflow platform and a system for ensuring stability of the underlying software and data [23].
Building an analysis environment that guarantees good performance for a wide user base is especially challenging. In the case of a managed service for genomics, the more successful the service is in attracting users, the more likely it is that performance will suffer due to the number of users, particularly as those users explore larger data sets through a wider range of analysis options [24]. Good performance on a per-user basis is a combination of available resources, user access to those resources, underlying infrastructure limits and bottlenecks (for instance, disk I/O), and the inherent scalability of the environment. We would argue that performance in the context of a widely available, flexible genomics environment requires high-availability, scalable back-end compute resources. We will discuss performance design principles and implications in more detail in a later section, as this is a particularly challenging but critical characteristic of an environment that aims to support large genomics data analysis.
As users become more sophisticated in genomics analysis, they often move from a single intuitive analysis platform (such as Galaxy) to multiple platforms (R, command line, custom scripts) that provide more capability and flexibility (generally at the expense of simplicity). Therefore, a design principle for a general genomics environment should be for that environment to be able to be used for training (implying at least an accessible platform), but able to scale in flexibility by adding more options for interaction (such as command line and/or programmatic interfaces), and scale computationally to provide the performance for real data analysis. For all levels of the environment, we would provide high capability through access to best practice tools and availability of reference datasets, and ideally linked to low latency visualisation and data interpretation services.
In response to the described circumstances, we developed the Genomics Virtual Laboratory (GVL). The GVL is designed to be a comprehensive genomics analysis environment supporting accessible best practice genomics for as wide a community of researchers as possible; this philosophy directs the design and implementation of the GVL to a great extent, as accessibility, flexibility, performance and wide availability are principal drivers. In practice, the GVL is a combination of scalable compute infrastructure, workflow platforms, genomics utilities, and community resources.
The primary objective of the GVL is to enable researchers to spawn and/or access automatically configured and highly available genomics analysis tools and platforms as a versatile workbench. Workbench instances may be centrally-managed servers or standalone and dedicated cloud-based versions. Either option is scalable and comes pre-populated with field-tested and best-of-breed software solutions in genomics, increasing reproducibility and usefulness of the solution. The aim is to offer a true genomics workbench suitable for bioinformatics data analysis for users with a variety of needs.
The choice of the components were based on a number of factors, including platform functionality, platform maturity, community uptake and complementarity (e.g. Galaxy is focussed on bioinformatics workflows and easy access to tools; IPython Notebook [34] on programmatic analyses; RStudio Server ( ) on statistical analyses; UCSC genome browser is perhaps the most popular genome browser). In the case of a decision on management middleware for deploying the platforms, CloudMan [35] has been demonstrably successful in providing cloud-based genomics workflow platforms based on Galaxy [29] and was therefore the software of choice for this role. Additionally, local expertise was a factor in the final design decisions of the GVL workbench (e.g., tutorials).
Finally, the GVL appeals to research infrastructure bodies and research institutions because it promotes democratized access to large scale, complex genomics analysis infrastructure. It focuses on simple and cost effective scaling (both in breadth and depth) of national computational infrastructure by delivering accessible and powerful solution to genomics researchers.
(a) A user initiates the launch process via the launch service (launch.genome.edu.au) by providing their cloud credentials to the launcher application and (b) within a few minutes is able to access the management interface (CloudMan) on the deployed instance of the workbench. (c) After workbench services have started, the researcher can use the applications as desired (e.g., Galaxy).
Community resources and support in the form of comprehensive online teaching materials around common genomics experimental analyses, supported with a mechanism of delivering those to the bioinformatics community:
The open build system of the GVL, and the general applicability of the cluster-on-the-cloud and service management model, make the GVL a good starting point for the development of other cloud-based research environments. Labs or developers can thus take the core GVL and customise it or extend it to meet their particular needs. This capability has already been exploited within the GVL project itself: genomics researchers often work in a specific sub-domain, each of which requires specific set of tools. Using the GVL's flexible build system, we are developing specialised "flavours" of the GVL workbench suitable for particular uses. The following flavours are currently under development and more are planned (in addition, community-contributed flavours are welcomed):
