UMIErrorCorrect

UMIErrorCorrect performs clustering of unique molecular identifiers (UMIs), error correction, and variant calling on UMI-containing sequencing reads to improve detection of low-frequency mutant alleles such as those in cell-free DNA from liquid biopsies.

Key Features:

• Input Flexibility: Requires only FASTQ files as input.
• Integrated Workflow: Integrates alignment, UMI clustering, error correction, and variant calling within a single pipeline.
• Error Correction and Sensitivity: Leverages UMIs to enhance accuracy and sensitivity of variant detection, improving detection of low-frequency alleles.
• Validation and Performance: Validated with cell-free DNA reference material containing known mutant allele frequencies (0%, 0.125%, 0.25%, and 1%) and public datasets, demonstrating superior variant detection across targeted sequencing protocols.
• Customization and Flexibility: Adaptable to data from various library preparation protocols and enrichment chemistries that utilize UMIs.

Scientific Applications:

• Liquid biopsy analysis: Detection of low-frequency mutant alleles in cell-free DNA from liquid biopsies.
• Targeted sequencing assays: Sensitive variant calling in targeted sequencing protocols that employ UMIs.
• Research and clinical genomics: Use in both basic research and clinical applications requiring high-sensitivity UMI-based sequencing analysis.

Methodology:

Accepts FASTQ input and performs alignment, UMI clustering, error correction, and variant calling.
