Visualization of data types such as coverage tracks, peak calls, and chromatin interactions remains an essential analytical procedure in genomic research. The new software package provides a unified programmatic framework aimed at facilitating the generation of clear, publication-quality illustrations directly within standard analysis environments.
The package addresses key operational limitations found in existing graphical interfaces and programmatic software. While established interactive genome browsers like the Integrative Genomics Viewer and the UCSC Genome Browser facilitate user-friendly exploration of genomic tracks, they are not optimized for fully programmatic and reproducible generation of publication-ready figures.
To overcome configuration overhead, trackDJ prioritizes usability by favoring convention over extensive configuration. The tool supplies high-level plotting functions equipped with sensible default parameters.
Within its unified plotting environment, trackDJ allows researchers to stack and coordinate multiple epigenomic data modalities simultaneously. Users can combine and align coverage tracks, peak annotations, chromatin loops, and standard gene annotations within the same visual layout.
The software package also incorporates flexible locus selection mechanisms to simplify data navigation. Users can specify genomic target regions either by exact coordinates or directly by gene name.
The authors note that trackDJ complements existing epigenomics toolkits by serving as a user-friendly, reproducible alternative to interactive genome browsers. By supporting scripted creation of clean and customizable genomic illustrations, trackDJ integrates directly into R-based computational workflows to streamline figure production across genomics studies.
