The Bioconductor project is an initiative for the collaborative creation of extensible software for computational biology and bioinformatics. The goals of the project include: fostering collaborative development and widespread use of innovative software, reducing barriers to entry into interdisciplinary scientific research, and promoting the achievement of remote reproducibility of research results. We describe details of our aims and methods, identify current challenges, compare Bioconductor to other open bioinformatics projects, and provide working examples.

Bioconductor

Bioconductor is a free , open source and open development software project for the analysis and comprehension of genomic data generated by wet lab experiments in molecular biology. Bioconductor is based primarily on the statistical R programming language , but does contain contributions in other programming languages. It has two releases each year that follow the semiannual releases of R. At any one time there is a release version , which corresponds to the released version of R, and a development version , which corresponds to the development version of R. Most users will find the release version appropriate for their needs. In addition there are many genome annotation packages available that are mainly, but not solely, oriented towards different types of microarrays. While computational methods continue to be developed to interpret biological data, the Bioconductor project is an open source software repository that hosts a wide range of statistical tools developed in the R programming environment. Utilizing a rich array of statistical and graphical features in R, many Bioconductor packages have been developed to meet various data analysis needs. As a result, R and Bioconductor packages, which have a strong computing background, are used by most biologists who will benefit significantly from their ability to analyze datasets. All these results provide biologists with easy access to the analysis of genomic data without requiring programming expertise.

Bioconductor have experienced difficulties downloading and installing both R and the Bioconductor modules.

The Bioconductor project aims to develop and share open source software for precise and repeatable analysis of biological data. We foster an inclusive and collaborative community of developers and data scientists. Software , Annotation and Experiment Packages. Docker Containers for Bioconductor. Bioconductor Books.

The mission of the Bioconductor project is to develop, support, and disseminate free open source software that facilitates rigorous and reproducible analysis of data from current and emerging biological assays. We are dedicated to building a diverse, collaborative, and welcoming community of developers and data scientists. Scientific , Technical and Community Advisory Boards provide project oversight. The Bioconductor release version is updated twice each year, and is appropriate for most users. There is also a development version , to which new features and packages are added prior to incorporation in the release. A large number of meta-data packages provide pathway, organism, microarray and other annotations. The Bioconductorproject started in and is overseen by a core team. A Community Advisory Board and a Technical Advisory Board of key participants meets monthly to support the Bioconductor mission by coordinating training and outreach activities, developing strategies to ensure long-term technical suitability of core infrastructure, and to identify and enable funding strategies for long-term viability.

The Bioconductor teaching committee is a collaborative effort to consolidate Bioconductor-focused training material and establish a community of Bioconductor trainers. We define a curriculum and implement online lessons for beginner and more advanced R users who want to learn to analyse their data with Bioconductor packages. It is currently chaired by Charlotte Soneson and Laurent Gatto. Membership is open to everybody interested in contributing and joining the discussion during the monthly meetings announced on the Google group, see below. This meta-repository is used for general discussions. The respective lessons are developed as modules in their own repositories. There are no pre-requisites for this module, and the materials assume no prior knowledge about R and Bioconductor.

The graph package was written from scratch for this project, but the other two are interfaces to rich libraries of software routines that have been created by other software projects, BOOST [ 31 , 32 ] and Graphviz [ 23 ] respectively, both of which are very substantial projects with large code bases. Efficiency of development By development, we refer not only to the development of the specific computing resource but to the development of computing methods in CBB as a whole. Consequently, the reader has painfully to re-implement the author's work before verifying and utilizing it We began with the perspective that significant investment in software infrastructure would be necessary at the early stages. Distributed development and recruitment of developers Distributed development is the process by which individuals who are significantly geographically separated produce and extend a software project. Object-oriented programming support The complexity of problems in CBB is often translated into a need for many different software tools to attack a single problem. Git Source Control. In addition it is important to keep a searchable archive available so that the system itself has a memory and new users can be referred there for answers to common questions. In many cases they also use private email, telephone and meetings at conferences in order to engage in joint projects and to keep informed about the ideas of other members. R 0 0 0 0 Updated Mar 3, There are likely to be strategies, concepts and methodologies that are standard practice in that domain that we are largely unaware of. There is a great deal of support in the language for creating, testing, and distributing software in the form of 'packages'. R has well-established interfaces to Perl, Python, Java and C.

The following are some of the many ways you can connect with the Bioconductor community. This includes our support site for most questions about using packages, a number of community forums for connecting about research and analysis, literature references, and developer outlets for questions about package developmenet and enhancements. Please remember when posting a question or response to abide by the Bioconductor Code of Conduct.

Modularization can occur at various levels of system structure. Figure 2 shows clearly that these two groups can be distinguished in terms of gene expression. Software modules can be acquired and installed interactively using, for example perl -MCPAN -e shell. The hgu95av2 package is one of a large collection of related packages that relate manufactured chip components to biological metadata concerning sequence, gene functionality, gene membership in pathways, and physical and administrative information about genes. Correspondence to Robert C Gentleman. These tools provide simple interfaces that allow for high-level experimentation in parallel computation by computing on functions and environments in concurrent R sessions on possibly heterogeneous machines. Use Bioc 'devel'. On the client side, the user does not need to learn about the storage or internal details of the data packages.

Several members of the Bioconductor development team have taught courses and subsequently refined the material, based on success and feedback. This approach has been used by the R project for approximately 10 years.
