A single **R** script can contain all steps of a complete analysis, making it simple to document, reproduce or share the workflow containing all relevant details. The `QuasR` package integrates the functionality of several **R** packages (such as `IRanges` and `Rsamtools`) and external software (e.g. `bowtie`, through the `Rbowtie` package). The package was originally created for in house use at the Friedrich Miescher Institute. Current contributors include: - [Michael Stadler]( - Dimos Gaidatzis - [Charlotte Soneson]( - Anita Lerch - Florian Hahne ## Functionality The current `QuasR` release supports the analysis of single read and paired-end ChIP-seq (chromatin immuno-precipitation combined with sequencing), RNA-seq (gene expression profiling by sequencing of RNA) and Bis-seq (measurement of DNA methylation by sequencing of bisulfite-converted genomic DNA) experiments. Allele specific alignment and quantification is also supported in all of these experiment types. `QuasR` has been successfully used with data from Illumina, 454 Life Technologies and SOLiD sequencers, the latter by using bam files created externally `QuasR`. ## Reference `QuasR` has been described in: "QuasR: Quantify and Annotate Short Reads in R" Gaidatzis, D. and Lerch, A. and Hahne, F. and Stadler, M.B. *Bioinformatics* **2015**, 31(7):1130-1132.
