BamSnap

BamSnap generates read-level visual snapshots from BAM files to enable manual inspection and validation of sequencing-based variant calls and genomic regions.

Key Features:

• Command-based operation: Operates via command-line invocation to produce visualizations from indexed BAM files.
• Graphics library with BAM indexing: Uses graphics libraries combined with BAM indexing to rapidly render high-quality snapshot images.
• Customizable tracks and layouts: Supports customization of tracks and layout within generated images to focus on specific read- or region-level details.
• Scalability: Has produced read-level images for over 2,500 whole genomes across 1,000 genomic loci, demonstrating capability to handle large datasets.

Scientific Applications:

• Variant validation: Facilitates verification of variant calls by visual inspection of sequencing reads in BAM files.
• Complex locus analysis: Enables exploration of complex genomic regions using read-level visualizations to assess mapping and variant context.
• Large-scale genomic studies: Supports visualization and quality assessment across many whole-genome samples and loci for cohort analyses.
• Clinical genomics: Provides read-level evidence to aid interpretation of genetic variation in clinical genomics workflows.

Methodology:

Combines graphics libraries with BAM indexing to render detailed read-level snapshots and customizable layouts.
