rseqc-redux 5.0.2

RNA-seq Quality Control — modernized fork of RSeQC

rseqc-redux

rseqc-redux is a modernized fork of RSeQC (RNA-seq Quality Control), originally by Liguo Wang. It updates the RSeQC 5.0.1 codebase with modern Python packaging, comprehensive tests, and CI — while preserving the original functionality.

Requirements

• Python 3.10 or higher
• Indexed BAM files (.bam with corresponding .bam.bai index files)
• A BED-format gene model / reference annotation

Dependencies

Core dependencies are automatically installed:

• pysam — BAM/SAM file handling
• bx-python — Interval indexing and overlap
• numpy — Numerical operations
• pandas — Data frame operations (single-cell modules)
• pyBigWig — BigWig file I/O
• matplotlib / logomaker — Plotting

Installation

From PyPI (Recommended)

pip install rseqc-redux

From Source

git clone https://github.com/semenko/rseqc-redux.git
cd rseqc-redux
pip install .

Development Installation

git clone https://github.com/semenko/rseqc-redux.git
cd rseqc-redux
uv sync

Quick Start

# Basic BAM statistics
bam_stat -i sample.bam

# Infer RNA-seq strandedness
infer_experiment -r gene_model.bed -i sample.bam

# Transcript integrity number
tin -i sample.bam -r gene_model.bed

# Gene body coverage
geneBody_coverage -r gene_model.bed -i sample.bam -o output

# Read distribution over genomic features
read_distribution -r gene_model.bed -i sample.bam

# Junction annotation
junction_annotation -r gene_model.bed -i sample.bam -o output
