Annotation-agnostic differential expression analysis of RNA-seq data at base-pair resolution via the DER Finder approach. This package contains two different implementations of this approach. The first one is the single base-level F-statistics implementation and the second one is via identifying expressed regions. For more information about derfinder check the vignettes here.

Documentation

For more information about derfinder check the vignettes through Bioconductor or at the documentation website.

Further documentation

You can generate HTML reports from the results using regionReport available here.

Installation instructions

Get the latest stable R release from CRAN. Then install derfinder using from Bioconductor the following code:

if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager")

BiocManager::install("derfinder")

Please note that the derfinder was only made possible thanks to many other R and bioinformatics software authors, which are cited either in the vignettes and/or the paper(s) describing this package.

DER Finder versions

  • The original implementation of the DER Finder approach as published in Frazee et al, Biostatistics 2014 is available via GitHub at derfinder.
  • The version implementing the single base-level approach via calculating F-stastics as described in the pre-print Collado-Torres et al, Nucleic Acids Research 2017 is available via Bioconductor at derfinder. The same package has the functions required for the expressed regions-level approach.

Code of Conduct

Please note that the derfinder project is released with a Contributor Code of Conduct. By contributing to this project, you agree to abide by its terms.
