RegTools

Tools that integrate DNA-seq and RNA-seq data to help interpret mutations in a regulatory and splicing context.

Features

• Identify evidence for aberrant splicing in RNA reads near a list of variants.
• Extract exon-exon junctions from a RNAseq BAM file.
• Annotate exon-exon junctions with information from a known transcriptome.
• Annotate variants with splice-region(the definition of this region is configurable) annotations.

Hardware requirements

RegTools requires only a standard computer with enough RAM to support the in-memory operations.

Software requirements

OS Requirements This package is supported for macOS and Linux. The package has been tested on the following systems:

macOS: macOS 10.12 (Sierra), macOS 10.13 (High Sierra), macOS 10.14 (Mojave), macOS 10.15 (Catalina), macOS 11 (Big Sur), macOS 12 (Monterey)

Linux: Ubuntu 16.04, Ubuntu 18.04, Ubuntu 20.04

Installation

Clone and install regtools by running the following:

    git clone https://github.com/griffithlab/regtools
    cd regtools/
    mkdir build
    cd build/
    cmake ..
    make

Installation should take 1-5 minutes.

For convienience we also maintain a docker image available at https://hub.docker.com/r/griffithlab/regtools/

Usage:

    regtools --help

If one wishes to test their installation, we include test data under test_data.

Here's an example command using that data along with the example output. This should run in under a minute.
