AirLift

AirLift remaps sequencing reads between reference genomes to update mapped read sets when reference assemblies are revised.

Key Features:

• Efficiency: Reduces execution time for remapping between similar references by up to 27.4 times compared to full re-mapping.
• Accuracy: Ensures high-accuracy identification of single nucleotide polymorphisms (SNPs) and insertions/deletions (INDELs), with validation reported using Genome Analysis Toolkit (GATK).
• Reference-similarity remapping: Exploits similarities between consecutive reference genomes to update existing mappings rather than performing full re-mapping.

Scientific Applications:

• Variant Calling: Supports precise identification of SNPs and INDELs by providing updated read mappings for downstream variant analysis.
• Comparative Genomics: Enables comparison of genomic data across different reference versions or closely related species by harmonizing read mappings.
• Longitudinal Studies: Maintains consistency of read mappings over time as reference genomes evolve, facilitating longitudinal analyses.

Methodology:

Leverages similarities between consecutive reference genomes to update existing mappings rather than performing full re-mapping, with variant validation performed using the Genome Analysis Toolkit (GATK).
