| ==Abstract==
| |
| '''Background''': Next-generation sequencing (NGS) has revolutionized how research is carried out in many areas of biology and medicine. However, the analysis of NGS data remains a major obstacle to the efficient utilization of the technology, as it requires complex multi-step processing of big data, demanding considerable computational expertise from users. While substantial effort has been invested on the development of software dedicated to the individual analysis steps of NGS experiments, insufficient resources are currently available for integrating the individual software components within the widely used R/Bioconductor environment into automated [[Workflow|workflows]] capable of running the analysis of most types of NGS applications from start-to-finish in a time-efficient and reproducible manner.
| |
|
| |
| '''Results''': To address this need, we have developed the R/Bioconductor package systemPipeR. It is an extensible environment for both building and running end-to-end analysis workflows with automated report generation for a wide range of NGS applications. Its unique features include a uniform workflow interface across different NGS applications, automated report generation, and support for running both R and command-line software on local computers and computer clusters. A flexible sample annotation infrastructure efficiently handles complex sample sets and experimental designs. To simplify the analysis of widely used NGS applications, the package provides pre-configured workflows and reporting templates for RNA-Seq, ChIP-Seq, VAR-Seq, and Ribo-Seq. Additional workflow templates will be provided in the future.
| |
|
| |
| '''Conclusions''': systemPipeR accelerates the extraction of reproducible analysis results from NGS experiments. By combining the capabilities of many R/Bioconductor and command-line tools, it makes efficient use of existing software resources without limiting the user to a set of predefined methods or environments. systemPipeR is freely available for all common operating systems from Bioconductor (http://bioconductor.org/packages/devel/systemPipeR).

| ==Background==
| |
| By allowing scientists to rapidly sequence and quantify DNA and RNA molecules, next-generation sequencing (NGS) technology has transformed biology into one of the most data intensive research disciplines. In the past, experiments have been performed on a gene-by-gene basis, while NGS has introduced an age where it is has become a routine to sequence entire transcriptomes, genomes, or epigenomes rather than their isolated parts of interest. It will soon be possible to conduct these experiments on large numbers of single cell samples<ref name="KaliskySingle11">{{cite journal |title=Single-cell genomics |journal=Nature Methods |author=Kalisky, T.; Quake, S.R. |volume=8 |issue=4 |pages=311–4 |year=2011 |doi=10.1038/nmeth0411-311 |pmid=21451520}}</ref><ref name="TrapnellTheDynamics14">{{cite journal |title=The dynamics and regulators of cell fate decisions are revealed by pseudotemporal ordering of single cells |journal=Nature Biotechnology |author=Trapnell, C.; Cacchiarelli, D.; Grimsby, J. et al. |volume=32 |issue=4 |pages=381–86 |year=2014 |doi=10.1038/nbt.2859 |pmid=24658644 |pmc=PMC4122333}}</ref> for a wide range of time points, treatments, and genetic backgrounds to study biological systems with greater resolution and precision.
