rowbowt

rowbowt leverages a pangenome index and a marker array to infer genotypes from short-read sequencing data, thereby reducing reference bias in variant calling.

Key Features:

• Pangenome Index Application: Uses a comprehensive pangenome index to infer genotypes from short-read sequencing data by representing multiple genomic variants simultaneously.
• Marker Array Structure: Introduces the marker array indexing structure to enable efficient and precise variant calling against large reference panels such as the 1000 Genomes Project.
• Reduction of Reference Bias: Avoids reliance on a single linear reference to reduce reference bias and improve accuracy of genotype inference.
• Performance Efficiency: Achieves faster processing times and reduced memory usage compared to existing graph-based methods, making it suitable for large-scale genomic studies.

Scientific Applications:

• Genomic Research: Applicable to high-throughput genotyping across diverse populations and large reference panels such as the 1000 Genomes Project.
• Population Genetics: Enhances representation of variant frequencies and distributions by reducing reference bias in population-level analyses.
• Clinical Genomics: Improves accuracy of genotype-based diagnostics from short-read sequencing data by providing more reliable variant calls.

Methodology:

Integrates a pangenome index with the marker array to map short reads against multiple reference sequences and consider numerous genomic variants simultaneously for genotype inference.
