Abstract
BackgroundHigh-throughput sequencing often provides a foundation for experimental analyses in the life sciences. For many such methods, an intermediate layer of bioinformatics data analysis is the genomic signal track constructed by short read mapping to a particular genome assembly. There are many software tools to visualize genomic tracks in a web browser or with a stand-alone graphical user interface. However, there are only few command-line applications suitable for automated usage or production of publication-ready visualizations.ResultsHere we present svist4get, a command-line tool for customizable generation of publication-quality figures based on data from genomic signal tracks. Similarly to generic genome browser software, svist4get visualizes signal tracks at a given genomic location and is able to aggregate data from several tracks on a single plot along with the transcriptome annotation. The resulting plots can be saved as the vector or high-resolution bitmap images. We demonstrate practical use cases of svist4get for Ribo-Seq and RNA-Seq data.Conclusionssvist4get is implemented in Python 3 and runs on Linux. The command-line interface of svist4get allows for easy integration into bioinformatics pipelines in a console environment. Extra customization is possible through configuration files and Python API. For convenience, svist4get is provided as pypi package. The source code is available at https://bitbucket.org/artegorov/svist4get/

High-throughput sequencing often provides a foundation for experimental analyses in the life sciences
Next-generation sequencing gave birth to multiple high-throughput methods of the life sciences, many of which are based on mapping short sequence reads to an existing genome assembly
Users preferring command-line utilities can use fluff [9] and ngs.plot [10]. These tools provide some advanced functions for data analysis but allow only a minimalistic approach to the visualization of genomic track segments in particular genomic windows
