HeurAA

HeurAA detects insertions and deletions (indels) in next-generation sequencing (NGS) amplicon reads to enable accurate variant identification in genomic and clinical studies.

Key Features:

• Heuristic amplicon alignment: Uses a heuristic alignment approach to compare amplicon reads with reference sequences for indel detection.
• High accuracy and speed: Detects a wide range of indels with high accuracy and processes data more than an order of magnitude faster than previous programs.
• Long-read compatibility: Compares reads and reference sequences up to several thousand base pairs in length.
• Complex mixture analysis: Identifies variants in complex mixtures containing reads from different gene segments and multiple samples, supporting multiplexed sequencing data.
• Implementation: Implemented in C and Perl and runs on Linux.

Scientific Applications:

• Cancer diagnostics and personalized medicine: Detects indels within PCR amplicons to support oncogene analysis and clinical variant identification in cancer studies.
• Validation on 454 sequencing: Validated using multiplex sequencing of 40 amplicons across 12 oncogenes in lung cancer cell lines sequenced on the 454 Genome Sequencer.
• Long-read genomic studies: Applicable to comprehensive genomic analyses involving long-read amplicon sequencing.

Methodology:

HeurAA applies a heuristic amplicon-alignment algorithm to align amplicon sequences to reference genomes for indel detection.
