trackplot

Trackplot generates integrative genomics viewer (IGV) style track plots, profile plots, and heatmaps from bigWig files for epigenomic data visualization.

Key Features:

• High Performance: Achieves performance gains of several magnitudes compared to equivalent R packages through reliance on bwtool.
• Minimal Dependencies: Requires only data.table and bwtool as primary dependencies, with plots generated in base R graphics eliminating the need for additional packages.
• Gene Model Integration: Queries the University of California Santa Cruz (UCSC) genome browser for gene models to enhance reproducibility of analyses.
• GTF Support: Extends support to general transfer format (GTF) files for enhanced versatility.

Scientific Applications:

• Epigenomic Data Visualization: Visualizes bigWig files to generate IGV-style track plots, profile plots, and heatmaps for epigenomic enrichment analysis.

Methodology:

Trackplot relies on bwtool for rapid bigWig file processing, queries the UCSC genome browser for gene models, and generates plots using base R graphics.
