Within the project, statisticians devoted to method development work together with statistical geneticists and biologists to refine existing statistical methods as well as develop new ones and make them applicable to genomic analysis.
The GenABEL Tutorial
LCK drafted the initial version of the manuscript and analyzed the data. Most scientific software is written by only a few authors, often a student working on a thesis.
With the advent of polyphenotype analysis as is now customary in e. An up-to-date list of the packages in the suite can be found on http: Furthermore, our open development process has resulted in transparent development of methods and software, including public code review, a thtorial fraction of bugs being submitted by members of the community, and quick incorporation of bug fixes. Having an open forum serves various purposes.
The GenABEL Project for statistical genomics
This was achieved by using optimal hardware-tailored algorithms using state-of-the-art linear algebra kernels, incorporating optimizations and avoiding redundant computations. It contains a high-performance computing based approach facilitating extremely fast mixed-model based regression of multiple omics traits like metabolomics or lipidomics on imputed genotype data Developer discussions take place on a dedicated mailing list, and development is further supported by robust development practices including use of public version control, code review and continuous integration.
Moreover, our experience shows that once the peer-reviewed article describing a tool has been published, funding and time to continue development and support of that tool are usually limited or non-existent, and consequently, the tool often slowly fades into oblivion.
Agile methods in biomedical software development: I retain this article, the tools and the information provided of extreme importance to the scientific community. The field of statistical gen- omics lies at the heart of current research into the genetic aetiology of human disease and personalized or precision medicine 1.
I have read this submission. The authors declare no conflicts of interest in the authorship or publication of this contribution. This very well written article tuotrial the GenABEL project for statistical tktorial and high lightens the great success of the project, that in the years has lead to the creation of turorial actual scientific community that is spread in several countries worldwide.
It enables a free flow of information between the layers in the project resulting in rapid feedback between the various levels. Approved Giulietta MinozziReferee 1.
No competing interests were disclosed. Other packages are planned to be added before the end of Indeed, this is reflected by more than citations according to google scholar for the original GenABEL paper published in N Engl J Med. This flow of work and information is not linear, but rather more circular in nature, with information and feedback being continuously transferred between the various layers as depicted in Figure 1. Accepted May Genomewide rapid association using mixed model and regression: Genome-wide association study identifies novel loci associated with circulating phospho- and sphingolipid concentrations.
Unfortunately, creators of scientific software are usually not funded to actively build such a community. Open source, Scientific software, Software development, Community building, Statistical genetics, Genomics, Statistical methodology.
Producing Open Source Software: A new initiative on precision medicine. Like the GenABEL package it allows running linear or logistic regression, as well as Cox proportional hazards model, however, ProbABEL is tailored to the large file sizes that are inherent to current data sets with approximately 30 million imputed genotypes per individual.
Nevertheless, despite limited amount of novel scientific ideas or scientific genahel in the current manuscript, the authors have clearly put a lot of work into creating a very impressive interactive user and developer community.
To this end all program code and documentation are either stored in a publicly readable instance of the Subversion version control system, with write access limited to a group of core contributors, or on GitHub https: Torvalds L, Diamond D: Lastly, to reiterate, the GenABEL is a very impressive large scale project that is heavily used by the community!

Currently, a total of 94 bugs have been submitted to the bug trackers on R-forge and GitHub since their opening in andrespectively. Using Jenkins various tests e. The total number of visits in that period wasof which came from unknown cities.
Increasing the power of genome wide association studies in natural populations using repeated measures-evaluation and implementation. It is my understanding that the manuscript is aimed at reaching potential new users, but even to old users, unaware of the possible new tools included in the GenABEL project.
