Hadoop-CNV-RF

Hadoop-CNV-RF detects small copy number variations (CNVs) in targeted next-generation sequencing (NGS) gene panels to provide scalable CNV analysis for clinical and research applications.

Key Features:

• Scalability: Leverages the Hadoop framework to distribute computation and overcome the memory limitations observed in CNV-RF when analyzing large gene panels.
• Distributed computing: Uses Hadoop's distributed processing model to run computations in parallel across multiple nodes.
• Runtime reduction: Reduces analysis time from approximately two days to under four hours through distributed processing.
• Clinical validation: Has undergone clinical validation and is employed in a CLIA-certified molecular diagnostics laboratory for CNV detection in targeted capture data.
• Targeted NGS compatibility: Detects small CNVs in clinically relevant genes from targeted capture and other NGS panel data.
• Algorithmic basis: Adapts the core algorithms of CNV-RF within a distributed computing environment.

Scientific Applications:

• Clinical diagnostics: Precise detection of CNVs in clinically relevant genes to inform diagnosis of genetic disorders from targeted NGS panels.
• Large gene-panel analysis: Enables comprehensive CNV calling across extensive targeted gene panels that were impractical with CNV-RF due to scalability constraints.
• Genomic research: Supports scalable CNV analysis for research studies using targeted capture NGS datasets.

Methodology:

Adapts CNV-RF core algorithms within the Hadoop distributed computing environment to perform parallel processing across multiple nodes on NGS/targeted capture data.
