deBGA-VARA

deBGA-VARA is a software tool that aligns high-throughput sequencing reads to a reference genome while incorporating known genetic variations. It aims to improve the accuracy and sensitivity of read alignment and subsequent variant calling by utilizing existing variant information.

Key features of deBGA-VARA:

1. Integrates the Variation-Aware Read Alignment (VARA) algorithm into the deBGA aligner.

2. Construct a pseudo-tree-based structure on the fly for seed extension, dynamically extracting regional variants without loading the entire genome variation into memory.

3. Generates alignments between reads and multiple genomic sequences simultaneously using the Landau-Vishkin algorithm schema.

4. Maintains small memory footprints while improving variant calling accuracy.

5. Benchmarked on both simulated reads and the NA12878 sequencing dataset, demonstrating high sensitivity and accuracy.
