Rbwa

Rbwa wraps BWA alignment algorithms for use in R, enabling short-read and long-read sequence alignment against reference genomes.

Key Features:

• BWA-backtrack support: Provides access to the BWA-backtrack algorithm for aligning short reads.
• BWA-MEM support: Provides access to the BWA-MEM algorithm for aligning longer reads and split alignment.
• Index construction: Includes a convenience function to build a BWA index from a reference genome.

Scientific Applications:

• Short-read alignment: Aligns Illumina short reads to a reference genome using BWA-backtrack.
• Long-read and split-read alignment: Aligns longer sequences or sequences with structural variations using BWA-MEM.
• Reference genome indexing: Prepares BWA indices from reference genomes to enable efficient alignment workflows.

Methodology:

Rbwa functions as an R wrapper that interfaces with the BWA C implementation, exposing BWA-backtrack and BWA-MEM algorithms and index building functionality within the R environment.
