GW is a terminal-based genome browser designed for inspecting sequencing experiments and reviewing variants.
It provides an interactive graphical view for genomic data, supports common alignment and variant formats, and includes tools for tracks, image output, and labelling workflows used in bioinformatics analysis.
This is free and open source software.
Key Features
- Displays genomic sequencing alignments from BAM and CRAM files.
- Opens and annotates variants stored in VCF and BCF files.
- Shows multiple regions and multiple alignment files side by side in the same session.
- Adds extra tracks such as BED, VCF, BCF, LABEL, and image inputs.
- Exports static images in PNG and PDF formats for reports and sharing.
- Includes an interactive command box for navigation, filtering, counting reads, and taking snapshots.
