GenomeMapper

GenomeMapper maps short reads from genome resequencing projects to a graph-based representation of multiple genomes to detect polymorphisms and genetic variation.

Key Features:

• Multiple-genome mapping: Supports simultaneous mapping of short reads against multiple genomes by integrating related genomes into a unified graph structure.
• Graph-based representation: Constructs a graph-based representation that encapsulates multiple genomes to facilitate comparative analyses.
• Alignment modes: Performs both ungapped and gapped alignments of short reads.
• High throughput: Accommodates alignment of millions of reads for large-scale genome resequencing projects.
• Enhanced variant detection: Enables detection of polymorphisms and genetic variations that may be missed when aligning to a single reference genome.

Scientific Applications:

• Population genetics: Improves detection of allelic variation across individuals within a species.
• Evolutionary biology: Supports comparative analyses of related genomes to study genetic diversity and evolutionary relationships.
• Personalized medicine: Aids identification of disease-associated polymorphisms by mapping reads against multiple individual genomes.
• Phylogenetic analyses: Provides data on genome-wide variation to inform more accurate phylogenetic inferences.

Methodology:

Constructs a unified graph-based representation of multiple related genomes and performs ungapped and gapped alignments of short reads for simultaneous mapping across those genomes.
