The authors declare no conflicts of interest in the authorship or publication of this contribution. Development and application of genomic control methods for genome-wide association studies using non-additive models. 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.

DatABEL is an R interface to our filevector library which provides a file format that is optimised for fast access to data in matrix form, e.

The GenABEL Tutorial

The collaborative nature of the project is demonstrated in the GenABEL package as it implements several statistical methods developed within the framework, including approximate mixed models 21 — 23 and various methods for genomic control 24 Each tool in the GenABEL suite has its own documentation and the GenABEL Tutorial 27 with more than pages takes the user from learning basic R to performing more complicated analyses, showing how the various packages interconnect.

The source code for the other packages can be downloaded from our website at http: It includes functions to compute univariate and multivariate odds ratios of the predictors, the area under the receiver operating characteristic ROC curve AUCHosmer-Lemeshow goodness of fit test, reclassification table, net reclassification improvement and integrated discrimination improvement Archived source code at the time of publication https: All authors contributed to the review of the manuscript and agreed to the final content.

Using Jenkins various tests e. With the advent of polyphenotype analysis as is now customary in e.

Moreover, because genanel this openness results of the project i. Genome-wide association study identifies novel loci associated with circulating phospho- and sphingolipid concentrations. Each city name is followed by the two-letter ISO code of the country in which it is located. 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.

Many tools are R packages, however, this is not a requirement for inclusion in the suite.

tuorial The methodologies underlining the different tools and their potential applications are well described. Genome-wide association studies GWASgenotype imputation and next-generation sequencing NGS are just a few of the techniques used in this field that is driven by increasingly larger data sets 23.

It is the second most-used tool from the suite with more than citations according to Google Scholar Published online May A genomic background based method for association analysis in related individuals. No geanbel interests were tutofial. These users have contributed posts in topics, with an average 7. Moreover, several video tutorials are available online. However, the 11 packages presented in this paper have been published previously in some shape or form, albeit presumably not in their most recent version.

The code contained in the Org mode file and the data in the genable files listed above are in the public domain Creative Commons CC0 license and can be used without restriction. As indicated by its name, MixABEL is an R package for running genome-wide association analyses using mixed models in quantitative traits.

Indeed, this is reflected by more than citations according to google scholar for the original GenABEL paper tutoriap in The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript. Genomewide rapid association using mixed model and regression: Such heterogeneity is an indication of interaction between a genetic marker and either another marker or an unknown factor 16 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.

In short, it is a form of agile community-driven development 11 Unfortunately, creators of scientific software are usually not funded to actively build such a community. I have read this submission. As of April this list has 34 subscribers. Moreover, public access to the source code is genzbel important ingredient for active participation by people from outside the core development team and is paramount for reproducible research. The software tools developed withing the project collectively make up the GenABEL suite, which currently consists of eleven tools.

The Story of an Accidental Revolutionary. Most scientific software is written by only a few authors, often a student working on a thesis. Please review our privacy policy.

With the help of computer scientists and scientific software developers these mathematical models are then implemented into efficient and user-friendly software. The field of statistical gen- omics lies at the heart of genabell research into the genetic aetiology of human disease and personalized or precision medicine 1. These version control systems record any change to the files so they can easily be reviewed and reverted if necessary 729 GWAS usually involves meta-analysis of the gdnabel results of various cohorts.

J Am Med Inform Assoc. To this end all program code and documentation are tugorial 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: LCK drafted the initial version of the manuscript and analyzed the data.

This was achieved by using optimal hardware-tailored algorithms using state-of-the-art linear algebra kernels, incorporating optimizations and avoiding redundant computations.

N Engl J Med. This shows that the project is really a platform for implementation of statistical methods which removes the burden of thinking about data formats etc. For scientific software, however, this is less often the case.
