DRAGEN DNA Pipeline

DRAGEN DNA Pipeline

The DRAGEN DNA Pipeline accelerates the secondary analysis of NGS data. For example, the time taken to process an entire human genome at 30x coverage is reduced from approximately 10 hours (using the current industry standard, BWA-MEM+GATK-HC software) to approximately 20 minutes. Time scales linearly with coverage depth.

These pipelines harness the tremendous power of the Illumina DRAGEN Bio-IT Platform and include highly optimized algorithms for mapping, aligning, sorting, duplicate marking, and haplotype variant calling. They also use platform features such as hardware-accelerated compression and optimized BCL conversion, together with the full set of platform tools.

Unlike all other secondary analysis methods, DRAGEN DNA Applications do not reduce accuracy to achieve speed improvements. Accuracy for both SNPs and INDELs is improved over that of BWA-MEM+GATK-HC in side-by-side comparisons.

In addition to haplotype variant calling, the pipeline supports calling of copy number and structural variants as well as detection of repeat expansions.
