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.

Further documentation

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

Installation instructions

Get R 3.3.x from CRAN.

## From Bioconductor

## Suggested:
biocLite(c('derfinderPlot', 'regionReport'))
